Louis Leithold (San Francisco, United States, 16 November 1924 – Los Angeles, 29 April 2005) was an American mathematician and teacher. He is best known for authoring The Calculus, a classic textbook about calculus that changed the teaching methods for calculus in world high schools and universities.[1] Known as "a legend in AP calculus circles," Leithold was the mentor of Jaime Escalante, the Los Angeles high-school teacher whose story is the subject of the 1988 movie Stand and Deliver.[2]

Biography[edit]

Leithold attained master's and doctorate degrees from the University of California, Berkeley. He went on to teach at Phoenix College (Arizona)[1] (which has a math scholarship in his name[3]), California State University, Los Angeles, the University of Southern California, Pepperdine University, and The Open University (UK).[4] In 1968, Leithold published The Calculus, a "blockbuster best-seller" which simplified the teaching of calculus.[5]

At age 72, after his retirement[4] from Pepperdine,[6] he began teaching calculus at Malibu High School, in Malibu, California, drilling his students for the Advanced Placement Calculus, and achieving considerable success.[4] He regularly assigned two hours of homework per night, and had two training sessions at his own house that ran Saturdays or Sundays from 9AM to 4PM before the AP test.[7] His teaching methods were praised for their liveliness, and his love for the topic was well known.[5] He also taught workshops for calculus teachers.[7][8] One of the people he influenced was Jaime Escalante, who taught math to minority students at Garfield High School in East Los Angeles. Escalante's subsequent success as a teacher is portrayed in the 1988 film Stand and Deliver.[4]

Leithold died of natural causes the week before his class (which he had been "relentlessly drilling" for eight months[4]) was to take the AP exam;[4] his students went on to receive top scores.[8] A memorial service was held in Glendale, and a scholarship established in his name.[6]
