Pratt was a pioneer of the U.S. petroleum industry, and established his kerosene refinery Astral Oil Works in Brooklyn, New York. He then lived with his growing family in Clinton Hill, Brooklyn. An advertising slogan was "The holy lamps of Tibet are primed with Astral Oil." He recruited Henry H. Rogers into his business, forming Charles Pratt and Company in 1867. Seven years later, Pratt and Rogers agreed to join John D. Rockefeller's Standard Oil.
An advocate of education, Pratt founded and endowed the Pratt Institute in Brooklyn, now a renowned art college. He and his children built country estates in Glen Cove, New York, developments in what became known as the Gold Coast in the 1920s on the North Shore of Long Island. In 1916, Standard Oil had a steamship tanker, first of its class, built at Newport News, Virginia and named it in honor of Pratt after his death.
Early life and education 
Charles Pratt was born in Watertown, Massachusetts, one of eleven children. His father, Asa Pratt, was a carpenter. He spent three winters as a student at Wesleyan Academy (now Wilbraham & Monson Academy).
Marriage and family 
Pratt worked first in Boston, then moved to New York in 1850-1851. Soon after getting established there, in 1854 he married Lydia Ann Richardson (1835–1861). They had two children: Charles Millard Pratt (1855–1913) and Lydia Richardson Pratt (1857–1904) (who married Frank Lusk Babbott).
After his wife Lydia's early death in 1861, Pratt married her younger sister Mary Helen Richardson in September 1863. They had six children together:
- Frederic B. Pratt (1865–1945);
- Helen Pratt (1867–1949);
- George Dupont Pratt (1869–1935);
- Herbert L. Pratt (1871–1945);
- John Teele Pratt (1873–1927) and
- Harold I. Pratt (1877–1939)
Whale oil, petroleum, Astral Oil 
As a young man, Pratt joined a company in nearby Boston, Massachusetts that specialized in paints and whale oil products. In 1850 or 1851, he moved to New York City, where he worked for a similar company.
Pratt recognized the potential for replacement of whale oil with petroleum ("natural oil") distillates for lighting purposes. He became a pioneer of the petroleum industry as new wells were established in western Pennsylvania in the 1860s. He soon established his kerosene refinery Astral Oil Works in Brooklyn, New York. Pratt's product later gave rise to the slogan, "The holy lamps of Tibet are primed with Astral Oil."
Henry H. Rogers, Charles Pratt and Company 
In the mid-1860s, Pratt met two young men, Charles Ellis and Henry H. Rogers, in the area of the new oil fields of Venango County in western Pennsylvania. Previously, Pratt had bought whale oil from Ellis in Fairhaven, Massachusetts, his and Rogers' coastal hometown. They struck a deal and pre-sold the entire output of their small venture, Wamsutta Oil Refinery, to Pratt's company at a fixed price. But, Ellis and Rogers had no wells and were dependent upon purchasing crude oil to refine and sell to Pratt. A few months later, crude oil prices suddenly increased due to manipulation by speculators. The young entrepreneurs struggled to live up to their fixed-price contract with Pratt, but soon their surplus of funds was gone and they were heavily in debt to Pratt.
Ellis gave up, but in 1866, Rogers went to Pratt in New York City to say he would take personal responsibility for the entire debt. Impressed, Pratt immediately hired Rogers for his own organization. Pratt made Rogers foreman of his Brooklyn refinery, with a promise of a partnership if sales ran over $50,000 annually. Rogers moved with his young family to the Greenpoint section of Brooklyn. He advanced from foreman to manager, and then was promoted to superintendent of Pratt's Astral Oil Refinery.
Pratt soon gave Rogers an interest in the business. In 1867, with Rogers as a partner, Pratt established the firm of Charles Pratt and Company. According to Elbert Hubbard, a journalist, in the next few years Rogers became Pratt's "hands and feet and eyes and ears."
Standard Oil 
In the early 1870s, Pratt and Rogers became involved in conflicts with John D. Rockefeller's South Improvement Company. Rockefeller had obtained favorable net rates from the Pennsylvania Railroad (PRR) and other railroads through a secret system of rebates. His actions outraged independent oil producers and refineries in western Pennsylvania and other areas. The New York interests formed an association, and about the middle of March 1872, sent a committee of three, with Rogers as head, to Oil City, Pennsylvania to consult with the Oil Producers' Union.
Working with the Pennsylvania independents, Rogers and his associates forged an agreement with the PRR and other railroads; the railroads eventually agreed to open rates to all and promised to end their special dealings with South Improvement. The oil men felt victorious, but Rockefeller had already begun to buy up opposing interests in the formation of Standard Oil.
A short time later, Rockefeller approached Charles Pratt with plans for cooperation and consolidation. Pratt and Rogers decided that the plan would benefit their business plans. Rogers formulated terms which guaranteed financial security and jobs for Pratt and him, which Rockefeller accepted. Charles Pratt and Company (including Astral Oil) became one of the important former independent refiners to join Rockefeller's organization; it became part of the Standard Oil Trust in 1874. Pratt's eldest son, Charles Millard Pratt (1855–1935), became Secretary of Standard Oil, and in 1923 his son Herbert Lee Pratt rose to become head of Standard Oil of New York.
Although the merger made Pratt a wealthy man, as a member of the board of directors of Standard Oil, he maintained his independence and frequently criticized Rockefeller. With Pratt's death in 1891, Rockefeller's position as the most powerful man in the oil industry, already well established, became unassailable.
Legacy and honors 
Charles Pratt is credited with recognizing the growing need for trained industrial workers in a changing economy. In 1886, he founded and endowed the Pratt Institute, which opened in Clinton Hill, Brooklyn in 1887. Originally a technical institute, it has become a renowned art, design and architectural college.
Long Island mansions 
Pratt moved to a country home in Glen Cove, New York about 1890. To provide for his children, he purchased large tracts of land surrounding his estate, totaling 1,100 acres (4.5 km²). He died the next year, aged 60, in New York City.
Charles Pratt's six sons and two daughters later built their own family estates in Glen Cove. As of 2004, most of the extant Pratt mansions along the Gold Coast are still in use:
- Welwyn, originally the home of Harold I. Pratt, is owned by and operated as the Nassau County Museum of Art.
- The Braes, originally owned by Herbert L. Pratt, is now the Webb Institute of Naval Architecture and Marine Engineering.
- The Manor House, built for John Teele Pratt, is now the Glen Cove Mansion Hotel & Conference Center.
- Poplar Hill, the Frederic B. Pratt house, is now the Glengariff Healthcare Center, housing both Glengariff, a long-term nursing care facility and the Pratt Pavilion for Nursing and Rehabilitation, a state-of-the-art, short-term, sub-acute rehabilitation center.
- Killenworth, originally the house of George Dupont Pratt, has, since the mid-20th century, been the country retreat for the Russian Delegation to the United Nations.
Pratt Cemetery 
With so many Pratt family members in Glen Cove, they had a cemetery built for themselves on their property. Known as "Pratt Cemetery", behind ornate gates and up a winding drive stands a pink granite Romanesque mausoleum designed by William Tubby, as well as a crypt and a tower connected by a "bridge of sighs". Charles Pratt is interred in a sarcophagus here, as are seven out of his eight children, and many of his grandchildren.
Other notable Pratt descendants 
- Andy Pratt (born 1947 in Boston), a great-grandson whose father Edwin H Baker Pratt was headmaster of the school Buckingham Browne & Nichols, is a singer-songwriter
- Sherman Pratt (1900–1964), founder of Florida's Marineland
Steamship tanker S.S. Charles Pratt 
In March 1916, Newport News Shipbuilding and Dry Dock Company launched the S.S. Charles Pratt, a tanker of 8,807 tons with a capacity of 119,410 barrels (18,985 m3) of oil. It became the first ship of the Pratt class, and was joined by the S.S. H.H. Rogers in May, 1916.
After 1939, both ships were operated by Panama Transport Co., a subsidiary of Standard Oil of New Jersey. At the beginning of World War II, on December 21, 1940, the S.S. Charles Pratt was torpedoed and sunk by a German U-boat in the Indian Ocean 220 miles (350 km) off the coast of Africa while en route from Aruba to Freetown, Sierra Leone. Of the American crew of 42, only two men died.
