He was born Leo Adler in New York City to Isidor and Anna Adler, Jewish immigrants from Eastern Europe, in 1926. There is, however, confusion about his birth year; during his artistic career, Adler consistently listed 1934 as his year of birth. According to his son, he did so in order to make himself seem like a younger artist as he was beginning his career in art. Adler graduated from James Madison High School in Brooklyn in 1942 and served in the U.S. Army between 1943 and 1946, spending the final year of his service in Japan immediately after the end of World War II. In 1948, he graduated with a BA degree in English from Syracuse University. In 1948–1949, he hitchhiked west, working at a steel mill in Chicago and then living in the bohemian artist community near Monterey, California. In 1949–50, Adler briefly pursued graduate studies in literature at the Sorbonne in Paris before returning to New York City.
