Early life

Rosten was born into a Yiddish-speaking family in what is now Poland, but emigrated to the U.S. with his family in 1911 at age three. His parents were Samuel C. Rosten and Ida Freundlich Rosten, both trade unionists. They opened a knitting shop in the Greater Lawndale area of Chicago, where Rosten and his younger sister grew up among other working-class Jewish families. Like their neighbors, the children spoke both English and Yiddish. Rosten showed an interest in books and language very early, and began writing stories when he was only nine. He put himself through school and earned degrees from both the University of Chicago, where he obtained his doctorate, and the London School of Economics.

During the Depression, when he was unable to find other work, he taught English to recent immigrants at night. These experiences eventually became the source of his most popular works, The Education of H*Y*M*A*N K*A*P*L*A*N and The Return of H*Y*M*A*N K*A*P*L*A*N.

Scriptwriter

Rosten was a successful screenwriter. He wrote the story for The Dark Corner, a film noir starring Mark Stevens; and Lured, the Douglas Sirk-directed period drama featuring Lucille Ball. He is listed as one of the writers for Captain Newman, M.D. adapted from his novel of the same title. Other films: Mechanized Patrolling (1943) (as Leonard Q. Ross), They Got Me Covered (1943) (story) (as Leonard Q. Ross), All Through the Night (1942) (story) (as Leonard Q. Ross), The Conspirators (1944) (screenplay), The Velvet Touch (1948), Sleep, My Love (1948) (novel) (screenplay), Double Dynamite (1951)(story), Walk East on Beacon (1952), and Mister Cory (1957) (story).

Stories and books

Rosten is best remembered for his stories about the night-school "prodigy" Hyman Kaplan (first published in The New Yorker in the 1930s, and later reprinted in 1937 in two volumes—The Education of H*Y*M*A*N K*A*P*L*A*N and The Return of H*Y*M*A*N K*A*P*L*A*N, under the pseudonym Leonard Q. Ross).

He is also well-known for his encyclopedic volume The Joys of Yiddish (1968), a guide to the Yiddish language and to Jewish culture (as well as a source for anecdotes and Jewish humor). It was followed by O K*A*P*L*A*N! My K*A*P*L*A*N! (1976), and Hooray for Yiddish! (1982) , a humorous lexicon of the American language as influenced by Jewish culture. Another Rosten work is Leo Rosten's Treasury of Jewish Quotations.

Quotations

Among his own many quotations are: "A conservative is one who admires radicals centuries after they're dead," "Truth is stranger than fiction; fiction has to make sense," "We see things as we are, not as they are," and "I cannot believe that the purpose of life is to be happy. I think the purpose of life is to be useful, to be responsible, to be compassionate. It is, above all to matter, to count, to stand for something, to have made some difference that you lived at all."

At a tribute dinner to fellow humorist W. C. Fields, a youngish and reportedly nervous Rosten came up with the unscripted remark about Fields that "any man who hates dogs and babies can't be all bad." This statement is often misattributed to Fields himself.

Personal life

On March 30, 1935, Rosten married Priscilla Ann "Pam" Mead (1911—1959), a fellow graduate student at the University of Chicago and sister of anthropologist Margaret Mead. They had two daughters: Madeline Rosten and Margaret Ramsey Rosten; and a son, Philip Rosten (1938—1996), who in turn had 6 grandchildren: Josh and Ben Lee (Madeline), Seth Muir (Margaret), and Alexander, Carrie and Pamela Rosten (Phillip). Carrie followed in her grandfather's literary footsteps and has authored three books, including a young adult novel, Chloe Leiberman (Sometimes Wong). Leo's and Pam's marriage ended in divorce in 1959; she took her own life on December 1 the same year. Rosten's second wife, whom he married January 5, 1960, was Gertrude Zimmerman (1915—1995).

Rosten's obituary in The Independent on February 21, 1997, written by Chaim Bermant, describes his personality as follows:

"Rosten was an inveterate Anglophile. He had enjoyed his years at LSE, was amazed by the enthusiastic reception Kaplan had received in the English press, and returned to London whenever opportunity dictated and even when it didn't. He lived in considerable luxury in a penthouse flat in Sutton Place, one of the most exclusive areas of New York, and rented a mews flat in Mayfair. England represented the tranquillity he could not find in America. He loved to rummage in English bookshops and wear English clothes - he contrived to display a subdued elegance - to go to the London theatres and entertain and be entertained in London clubs. He himself was a member of the Savile, the Reform and the Garrick."

According to Alex Abella's Soldiers of Reason, Rosten was influential in forming the Social Sciences division of RAND Corporation.
