The son of a rabbi, Segal attended Midwood High School in Brooklyn and traveled to Switzerland to take summer courses. He attended Harvard College, graduating as both the class poet and Latinsalutatorian in 1958, and then he obtained his master's degree and a doctorate in comparative literature from Harvard University.
His first academic book, , revolutionized the great Roman comic playwright best known today as the inspiration for the Broadway hit, A Funny Thing Happened on the Way to the Forum. In 2001 Harvard published his The Death of Comedy, the all-encompassing literary history.
''Yellow Submarine''
In 1967, from the story by Lee Minoff, he was one of the writers of the screenplay for The Beatles' 1968 motion pictureYellow Submarine.
''Love Story''
In the late 1960s, Segal collaborated on other screenplays. He had also written a romantic story about a Harvard student and a Radcliffe student but failed to sell it. However, literary agent Lois Wallace at the William Morris Agency suggested he turn the script into a novel, and the result was a motion picture phenomenon titled Love Story. A New York Times No. 1 bestseller, the book became the top selling work of fiction for 1970 in the United States, and was translated into 33 languages worldwide. The motion picture of the same name was the number one box office attraction of 1970. The novel proved problematic for Segal. He acknowledged that its success unleashed "egotism bordering on megalomania" and he was denied tenure at Yale. Moreover, "Love Story" "was ignominiously bounced from the nomination slate of the National Book Awards after the fiction jury threatened to resign." Segal later said that the book "totally ruined me." Segal wrote more novels and screenplays, including the 1977 sequel to Love Story, titled Oliver's Story.
Writing and teaching after ''Love Story''
He wrote widely on Greek and Latin literature. He published a number of scholarly works as well as teaching at the university level. He acted as a visiting professor for the University of Munich, Princeton University, and Dartmouth College. His novel The Class, a saga based on the Harvard Class of 1958, was a bestseller, and won literary honor in France and Italy. Doctors was another New York Times bestseller.
Marathons
Segal was an accomplished competitive runner. He was a sprinter at Midwood High School, and ran the 2 mile at Harvard College. He began marathon running during his second year at Harvard when track and fieldhead coachBill McCurdy was impressed with how fast he had run 10 miles. Segal ran in the Boston Marathon almost every year from 1955 to 1975. He finished in 79th place at 3 hours, 43 minutes in his first attempt, and his best performance was in 1964 when he finished 63rd with a time of 2:56:30. He recounted that after one Boston marathon someone yelled "Hey, Segal, you run better than you write". Segal covered the marathon as a color commentator for telecasts of both the 1972 and 1976 Summer Olympics. His most notable broadcast was in 1972 when he and Jim McKay called Frank Shorter's gold-medal-winning performance. When an impostor, West German student Norbert Sudhaus, ran into Olympic Stadium ahead of Shorter, an emotionally upset Segal screamed "That is an impostor! Get him off the track! This happens in bush league marathons! Throw the bum out! Get rid of that guy!" Moments later, he personalized his on‑air remarks by saying "Come on, Frank! You won it! It's a fake, Frank!" Amby Burfoot called Segal's account "one of the most unprofessional, unbridled, and totally appropriate outbursts in the history of Olympic TV commentary", taking into consideration the fact that Segal had taught Shorter at Yale. In 2000, The Washington Post included the phrase among the 10 most memorable American sports calls.
Family
Segal was married to Karen Marianne James from 1975 until his death; they had two daughters, Miranda and Francesca Segal. Francesca, born in 1980, is a freelance journalist, literary critic, and columnist.
Death
Segal, who suffered from Parkinson's disease, died of a heart attack on January 17, 2010, and was buried in London. In a eulogy delivered at his funeral, his daughter Francesca said "That he fought to breathe, fought to live, every second of the last 30 years of illness with such mind-blowing obduracy, is a testament to the core of who he was – a blind obsessionality that saw him pursue his teaching, his writing, his running and my mother, with just the same tenacity. He was the most dogged man any of us will ever know."
