Yehuda Ben-Yishay was born on February 11, 1933 in Cluj, a city in the Transylvania region in western Romania. His father, Chaim Ben-Yishay, was a businessman; his mother Leah (Finkelstein) Ben-Yishay was a seamstress.
His family survived the Second World War largely unscathed. Although hundreds of thousands of fellow Romanian Jews died during the Holocaust, hundreds of thousands survived, especially in the southern part of Transylvania, where the family had moved just before the war.
The Ben-Yishays were zealous Zionists, and in 1946 they boarded a converted cattle ship with about 2,000 other Jews for Palestine. The British authorities had banned such mass migration and when Yehuda arrived he and his two brothers and sisters were separated from their parents when they were taken to refugee camps.

He later attended the Hebrew University in Jerusalem in the hope of studying psychology, but there was no one to teach it: Arab guerrillas had murdered the department head and several colleagues in 1948.
Dr. Ben-Yishay studied sociology instead, graduating in 1957. He received a scholarship to the New School for Social Research in Manhattan and arrived at the end of the year.
To cover his living expenses, he taught Hebrew and worked with retirees, including at a summer camp in Brewster, NY. There he met Myrna Pitterman know. They married in 1960 and had three sons, Ari, Ron and Seth. All survive him along with his brothers Israel and Meir; his sister Pnina; and eight grandchildren.
At the New School, Dr. Ben-Yishay headed by a German emigrant psychologist named Kurt Goldstein.
