Harold D. Prewitt, Jr (Hal) (born October 1, 1954 in Hutchinson, Kansas, U.S.) is a Race car driver, American businessman, inventor of personal computer products and early pioneer in the personal computer revolution. He resides in South Beach (Miami Beach, Florida) and Park City, Utah.[1]

Prewitt competes[1] in professional and occasionally in amateur race events and has driven in more than 150 Endurance racing (motorsport) or sprint races worldwide. He is a regular competitor in the Grand-Am Rolex Sports Car Series and at major international FIA road races. These include the 24 Hours of Daytona, 24 Hours Nürburgring, Dubai 24 Hour, 24 Hours of Barcelona, Silverstone Britcar 24-Hour and major races held at road course race tracks all over the world.

In the 1970s and 1980s he was one of the early creators[2] of personal computer products, developing popular software and hardware while helping build a new industry. This was the period during which the microcomputer was developed, the Altair 8800 was launched and Microsoft and Apple Computer were founded. He provided consulting services to IBM in the years just prior to the introduction of their first personal computer and is credited[3] with inventing hard disk drives and a local area network for their first portable and desktop series computers.

Skilled[3] in computer programming and engineering, Prewitt founded and managed a number of technology firms. The largest and best known was Core International, Inc, a developer of disk array, computer data storage and backup products. Prewitt was Chairman and Chief Executive Officer until 1993 when the company was sold[4] to Sony.

Prewitt is the Managing Member of Prewitt Enterprises, LLC, a Florida-based Agricultural and investment business. The agricultural part of the business grows oranges and at its peak produced more than 1.5 million half gallon cartons of orange juice with much of it used in Tropicana's Pure Premium.[1]

Early life[edit]

Prewitt grew up in the Daytona Beach, Florida area and lived there from 1963 to 1976. There he had his first exposure to auto racing; volunteering at Daytona International Speedway and never realizing that one day he would return to the track as a driver. He built his first computer in 1967 at 13. It performed simple math, which he disliked so much in school, and even operated his phonograph. This was eight years before Steve Jobs and Steve Wozniak built their first[5] computer or Bill Gates started Microsoft (1975).[6] Prewitt's seventh grade teacher nicknamed him "Hal" after the humanlike spaceship computer in the movie 2001: A Space Odyssey (film) because of his keen interest in computers.

1970 Cadet Captain Prewitt

He joined the Civil Air Patrol as a cadet and earned his way to the second highest rank (Cadet Lt. Colonel), learning leadership, search and rescue, about the military and the value of providing community service. Prewitt learned how to fly a plane, soloed at 16 and shortly thereafter earned his Private Pilots License at the youngest age allowed.[1][2][3]

As a teenager, Prewitt learned sailing, fishing, boating and Scuba diving. With his aptitude for technical endeavors, he developed skills in mechanics, engineering, electronics, navigation and construction. At 15, before he had a driver's license, he rebuilt the engine of a neighbor's Fiat after it was pronounced unsalvageable. For a year he drove the car along the back roads around Daytona. Later he sold it for a profit to a woman who used it as a racecar. After school and in summers, he worked at jobs building homes and in a restaurant washing dishes and cooking. In high school, he had more spending money than the average student because of a business he operated renting out the family houseboat.[1][2][3]

After graduating High School, Prewitt continued building boats, managing his business and began to focus on computer programming. Between 1972-1975 he learned FORTRAN, BASIC, COBOL, ALGOL, RPG and assembly language using an IBM 1130. In the early 1970s, Prewitt dreamed of designing, building and selling a generation of small business computers with a price tag much less than the going rate of $50,000. Convinced that he was on to something big, the young Prewitt sought venture capital to get his plans off the ground. "I was told that the personal computer would never come into existence. They turned me down cold. It was an uphill battle from there." says Prewitt.[2] In 1975, he built and added to his computer collection an Altair 8800 (widely recognized as the spark that led to the microcomputer revolution). That same year, at the age of 21, Prewitt obtained his first business applications customer when he sold, designed and wrote computer programs for the IBM 5100 and System/32 as part of the business he had started at age 16. Never far from his racing interest, he joined the Sports Car Club of America (SCCA) and participated in autocross events.[3]

Family[edit]

Prewitt was born in Hutchinson, Kansas, the eldest son of Harold Dean Prewitt, Sr (20 Nov 1931 – 01 Mar 1972)[7] and Helen Mary Savage (b.11 May 1927). He has brothers Paul, Brian and Keith. Prewitt's father joined the US Air Force underage at 13 years old using his older brother's ID and then switched to the US Navy at 17 serving in World War II and Korea. His father left the military after 18 years (1945–1962), did odd jobs and then worked as a mailman for the US Postal Service until his death. Prewitt's father was honored as a Kentucky Colonel by the Governor of Kentucky. His Mother was a Registered nurse and lives in the Daytona Beach, Florida area.[1][3]

Prewitt married his first wife Florine Andrews in August 1980 and divorced after 23 years in early 2004. They have two sons, Calvin and Tim. He married Corinne Brody (Loria) in October 2007. She has a son, Alex.[1]

Education[edit]

Prewitt attended All Souls Catholic School (1960–1963) in Sanford, Florida until 3rd grade while his father served in the military. He attended Port Orange Elementary School (1963–1965) from 3rd to 5th grade when his family moved to Allandale, Florida.[8] In 1966, his family moved to Ormond Beach, Florida where he attended Osceola Elementary (1965–1966), Seabreeze Jr. High (1966–1969) and then graduated from Seabreeze High School (1969–1972) in 1972.[8] At 16, he attended Burnside-Ott Aviation in Miami, Florida where he soloed. After high school, Prewitt attended Daytona Beach Community College (1972–1976) studying business and computer science but left without earning a degree. He transferred to Florida Atlantic University (1976–1978), Boca Raton, Florida where he continued his studies in business and computer science. Prewitt dropped out of college when his business consumed all his available time.[3]

School records show he did well in Effort, but had poor academic performance with major challenges reading, spelling and finishing assigned work in those classes on time. He often failed English, Humanities and courses that require intense reading comprehension while scoring A's in Art, Computer Science, Physics and Physical Education. In the 7th grade standardized California Achievement Test that measured reading, arithmetic and language he averaged 3 grades below his classmates.[1] Prewitt reported "guidance counselors and a few teachers advised to forget about college and to take up a simple career saying I would likely not succeed at something more advanced. This was understandable considering a few days ago I found my 1971 SAT scores that showed 390 verbal and 490 math (880 total)."[9]

Dyslexia[edit]

Prewitt is dyslexic and has difficulty reading and spelling. He reported, "Only recently did I figure out the cause. Even though a Jr High teacher suspected I was dyslexic, they decided likely not because I did not reverse letters enough. Unfortunately, dyslexia was not well recognized, properly diagnosed or treated in those days. Reading, spelling and writing continue to be very difficult. Maybe some of my successes were a result of not knowing or thinking anything was wrong and the determination to overcome whatever challenges we face in life."[1][9]

Careers[edit]

Prewitt's working career began at the young age of 13. He started in construction helping build homes for an Ormond Beach, Florida builder. He also worked busing tables and washing dishes before a promotion to cook at local popular restaurants "The Tropics" and "Julian's". At 16, Prewitt started his first business. While attending community college, he built boats, worked as a painter, an accountant and for the yard crew at Howard Boat Works, a marina where his family had made an investment. Prewitt's final jobs where he was employed by someone else were as a lab assistant helping students in his college and as a computer programmer for a company providing business applications on mainframes and mini computers. After 22 years old, his employment was limited to working for himself or businesses he owned.[1][2][3]

Prewitt started his first business when he was 16 and a junior in High School. "Ranger Systems", had four divisions: Ranger Manufacturing, Business World, Rent a Houseboat and Ranger Automotive Engineering.[2][3]

He used the manufacturing part of the business to build electronics, computers and fiberglass boats from 13' fishing runabouts to a 40' houseboat. Business World did marketing, printing and advertising. Prewitt wrote brochures, shot pictures, placed ads and ran a printing press. The biggest and most profitable division was Rent a Houseboat. Prewitt took the family boat and turned it into a rental business. He sometimes used a small boat to travel to school and quickly reach the houseboat. Prewitt did everything from writing contracts to maintenance. "I started the houseboat business to pay for a car," Prewitt says. The business had its drawbacks; Prewitt frequently missed classes to unstop a toilet or revive the boat engine. The automotive division focused on repairs.[2][3]

One of his teachers, Dr. Robert Cameron Jr., program manager of computer science at Daytona Beach Community College, remembers Prewitt as a go-getter. "He was always working on something and too busy learning on his own to bother with the course work", he says.[2][3]

Prewitt operated Ranger Systems from 1970 to 1975 until his focus switched to computer programming and the personal computer revolution.[2][3]

In 1975, Prewitt created a new company to continue his efforts building, selling, installing and programming computers. This was the period when he started developing storage devices which ultimately became his most successful products. Prewitt worked on the many personal computers of the day in addition to machines from IBM, Data General, DEC and others.

He had customers that were located from mid to south Florida in the manufacturing, hotel, service, legal, medical, construction and agricultural industries. Prewitt used his skill as a pilot to enable quick and efficient travel to their offices by initially renting aircraft and then using his own.[2][3]

After hiring employees to help with the high demands of his business while trying to attend college, Prewitt decided to spread the his workload by taking on a partner and creating Southeast Computer Consultants. The organization was started in late 1977, of proven computer professionals who had come together rather than work as independent consultants. Prewitt moved over some of his clients from his International Computer and also obtained IBM as a client in the years just prior to the introduction of their first personal computer. The business grew, but the hours were long, costs were high and profits were lower than expected.

In 1979, Prewitt decided to divide up the clients and dissolve the firm due to the difficulty of managing this type of business and his desire to focus on the high growth evolving personal computer industry. He planned to call the new firm, "Core International" and offered his partner half of the new business. However his partner declined and continued in the same line of work.[2][3]

3 time INC 500 Fastest Growing Company

In late 1979, Prewitt as sole owner created CORE from the assets of International Computer and Southeast Computer Consultants. Initially CORE was created as a for-profit association of owners and operators of small IBM computers. It sold mail-order computer supplies and developed software for users of the IBM 5100, 5110 and IBM 5120 systems, the forerunners of today's personal computers. He continued research and development on computer storage devices and decided to build his first product for the IBM 5100 series because the machines did not have hard disk drives.[3]

CORE's 1979-1985 Delray Beach, FL Two small homes converted to offices where 19 million dollars of products were designed and sold before moving to the new 60,000 sqft Boca Raton location. Prewitt lived here until growth pushed him out.

Prewitt contracted with Control Data Corporation to manufacture the key component. Even though it was a niche product, the product became popular almost overnight when IBM discontinued its 5100 series and their customers turned to CORE for parts and supplies. Within two years, Prewitt had sold $2.5 million worth of disk drives. CORE's second hardware and major software product also catered to the IBM orphans. It was a device and software that allowed IBM 5110/20 users to transfer data and programs from their old bulky computers into the new sleek personal computers, which in 1981 were revolutionizing the computer industry. CORE's software was called PC51 and allowed any DOS personal computer to use any BASIC program written for the IBM 5110/20 series computer and to run unmodified. Impressed, IBM approached Core to become an IBM dealer. Customers could buy an integrated IBM PC which completely replaced IBM's 5100 computers or optionally attach them to CORE's local area network connecting all machines. These were revolutionary products and CORE was the only source.[2][3]

The company expanded internationally to include offices in Europe and Asia. In 1986, Inc Magazine selected CORE as 21st in their annual list (Inc. 500) of the 500 fastest-growing private companies in the U.S.. By 1990, CORE was well known as an industry leading developer of disk array, computer data storage and backup products. Prewitt created numerous disk drives, controllers and authored many business software applications and utilities.[3] He became widely recognized as an expert, quoted in the press and gave speeches and lectures both domestically and abroad. A major effort of his was to educate the marketplace on the way a hard drive functioned, their importance in the computer system and how to obtain the best performance and reliability. COREtest, a computer program developed with his team, became the industry standard[10] and most often quoted benchmark used to test, evaluate and compare performance of hard disk drives.[2][3]

Many[3] of Prewitt's products were the first of their kind, had no direct competition and were widely regarded for their superior[11] performance and reliability. He was Chairman and Chief Executive Officer of CORE until 1993 when the company was sold[4] to Sony.[2][3]

Prewitt first became active in racing while growing up in Daytona Beach, Florida in the 1970s and driving in SCCA events. He became serious in 2004 after attending Skip Barber Racing School.[12] Today, Prewitt is a professional level driver in selected International and North American Endurance road race events supporting his sponsors and EveryLapCounts.com, a global fund raising effort for children's charitable causes. He enjoys Endurance rather than Sprint racing. Prewitt's primary talent is ability to bring home a win by clicking off laps and staying out of the pits, not damaging or killing the equipment. He owned and managed a race shop thereby bringing an additional perspective different from other drivers; Prewitt understands the engineering, physics and knows how to turn a wrench.[1]

Auto racing history:[1][13][14] As of January 2012, Prewitt qualified for a career total 170 races (138 Sprint and 32 Endurance) and drove in 16 endurance (24 hours or longer) events at 29 tracks. He has won numerous pole positions and podium finishes: 71 firsts, 25 seconds and 6 third places for 46% wins in 156 starts and for 66% podium finishes. He has a low 4.14% did not finish (DNF) incident rate.

Prewitt finished 3rd place overall in the 2011 Silverstone Britcar 24-Hour, 1st in class in the 2010 Dubai 24 Hour, 2nd in class at the 2009 24 Hours of Barcelona and 4th in class at the 2011 24 Hours of Nürburgring while driving for Marcos Racing International in a BMW 120d turbo diesel. He finished the 2007 Grand-Am season 27th (29th out of 187) in driver points in the GT Rolex Sports Car Series and 71st (84th out of 172) in driver points in the GS KONI Challenge Series.

Prewitt also raced in 10 of 13 Rolex Sports Car Series and 1 of 12 KONI Challenge Series season races. His best (Top Ten) class finishes in Rolex Sports Car Series were 6th at Circuit Gilles Villeneuve - Montreal, Quebec, Canada, 7th at Iowa Speedway - Newton, Iowa and 9th in the 24 hours of Daytona. He finished 4th in the KONI Challenge Series at Daytona International Speedway.

In 2006 and 2007, Prewitt won numerous 1st place and class wins while racing in Historic Sportscar Racing (HSR), ROLEX Endurance Series and the Historic GT Series. He won the 2006 National Auto Sport Association (NASA) National Championship at Mid-Ohio Sports Car Course while driving the historic Porsche 911 GT3 RS that won 2nd place in class for the 2003 24 Hours of Le Mans.

From 2004 to 2006, he captured numerous lap records in SCCA, PBOC and National Auto Sport Association (NASA) classes and was overall Winner in the PBOC 2005 & 2006 Race Series season.

Some of his well known team co-drivers include: Diego Alessi, Elliott Forbes-Robinson, David Murry, John Pew, Shawn Price, Karl Reindler, and Cor Euser.

Fishing[edit]

Prewitt has been widely regarded as one of the world's top Sport Fishermen.[15] Over the years, he caught and released more than one thousand Billfish with many of them tagged for science research. Most of these were captured "stand up", not using a fishing chair and on light tackle. Prewitt was selected as Atlantic Ocean Angler of the Year 1992, recognized and awarded by International Game Fish Association (IGFA) as the Angler who Tagged & Released the most Sailfish in 1990, 1991 and 1992 and White Marlin in 1992. In 1989, Power and Motoryacht Magazine[16] named him one of America's Top Ten Anglers of 1988.

In 1988, he won perhaps the most prestigious and competitive Big-game fishing tournament series in the world, The Bahamas Billfish Championship (BBC). This annual award recognizes the overall champion of six tournaments located in the Bahamas held on Bimini, Cat Cay, Walker's Cay, Berry Islands and the Abacos.

Prewitt has achieved one of the rarest feats in offshore ocean Billfishing. This is when an Angler catches any three of five Billfish (Blue Marlin, White Marlin, Sailfish, Spearfish or Swordfish) within a single day. He has attained five Grand Slams (3 fish) and two Super Grand Slams (4 fish), including both a Grand and Super Grand Slam in the same day. With Prewitt's skills, it was not unusual for him to catch and release at the same time, a double (2) or triple (3) of White Marlin or Sailfish, all while under the strict IGFA Tournament Rules.

He has won or placed in the top three positions in numerous world class tournaments. These include Cancun, Mexico Light Tackle, Walker's Cay Billfish, Bimini Big Game, Treasure Cay, Chub Cay and the Boy Scout USVI Open Tournaments.

Prewitt owned two sportfishing boats and each was named Megabyte; a 1983 46' Post and 1988 61' Jim Smith. Both have been extensively covered in magazines and broadcast TV shows. The Post was featured on the cover of the October 1988 issue of Motor Boating & Sailing Magazine and in a story of winning fishing boats. The Jim Smith, in addition to magazines, was featured in the ESPN coverage of the Boy Scout Tournaments and Mark Sosin's Saltwater Journal television shows.[17] Prewitt was unique among yacht owners or Billfisherman; knowing how to run and fix almost anything on the boat and with the ability to work as the captain, engineer or mate. Rarely seen on the social circuit and probably not recognizable at the cocktail receptions, Prewitt maintained a low profile dissimilar from the typical big boat Angler. He explains the secrets of success in the story "Byte for Bite", by Jan Fogt in Boating Magazine April 1987.[18]

Philanthropy[edit]

Prewitt served on the Board of Directors and as Trustee until 2003 of The Billfish Foundation (TBF). Founded in 1986 by his late and longtime friend Winthrop P. Rockefeller, TBF is the world's leading non-profit organization dedicated to conserving billfish and associated species worldwide which helps ensure healthy oceans and strong coastal economies. TBF's signature research project is the traditional tag and release program that uses the efforts of anglers to provide data and research to scientists and fisheries managers.[19]

Prewitt and his family or firms have both supported and made philanthropic gifts to The Billfish Foundation, Boy Scouts of USVI, Every Lap Counts,[20] which supports charitable causes for children through major international endurance auto races, Norton Museum of Art in West Palm Beach, Florida, Palm Beach County, Florida Science Fair, Summit Christian School in West Palm Beach, Florida, WXEL-TV in West Palm Beach, Florida, Miami Rescue Mission which provides care for the homeless, Salvation Army in Miami, Florida, Park City Museum in Park City, Utah, Utah Symphony in Salt Lake City, Utah and Deer Valley Music Festival in Park City, Utah[1][20][21]

Politics & Public Service[edit]

Beginning in the mid 90s, Prewitt served as a Commissioner on the Architectural and Code Enforcement Boards prior to his 2001 unopposed election to the Town Commission of Manalapan, Florida where he held office until the town was reapportioned. He was very active in the Town and greatly covered in local press in more than 39 stories.[22] Prewitt served on the Florida Atlantic University Executive Advisory Board and Palm Beach Countywide Beaches & Shores Council.[1]

Other Interesting Facts[edit]

In March 2009, Prewitt purchased[23] Governor and presidential candidate Mitt Romney's home[24] in Park City, Utah. The home was built by Romney in 1999, used to raise his family while President of the 2002 Winter Olympics, was the site of a number of political events and also served as the family's vacation residence from 1999 to 2009.[25]

Prewitt's wife, Corinne, is a graduate of the Wharton School, University of Pennsylvania and was an Assistant County Manager for the $7 billion Miami-Dade County government, overseeing strategic planning, human resources, and technology initiatives.[25]

Quotes[edit]

  • Learn from experiences and never make the same mistake twice. When we are old people will think we are very smart.
  • Do the best job at whatever you do and everyone will desire your services.
  • Money follows success, not the other way around.
  • Don't focus on making money. Concentrate on being successful and the money will follow.
  • People make a company. Without them there is nothing but an empty shell.
  • Drivers often receive more praise than we deserve. Endurance racing is a Team not a Driver's race. No single person wins it and any member can cause the loss. You win Endurance races by clicking off laps and staying out of the pits, not damaging or killing the equipment. It's nice, but you don't have to be the fastest driver on the track.
  • The best way to succeed, whether in racing, business or tasks in everyday life, is to develop the ability to see the future. Take in every piece of information, connect the dots and make the right decisions. When we don't make mistakes we look like a genius.
  • Increase your success when billfishing by creating a single weakest link, a bait that looks and swims different and that is chasing other bait.
