Born in Boston, Massachusetts. Married Thelma Leeds. They had four sons. Employed as advertising manager with Kane Furniture Company about 1923.

In 1929 he appeared on a radio show "The Roof At The Hotel Bradford." His career in comedy took off after he created the character "Parkyakarkus" based on Greek immigrants from his neighborhood. "The Parkyakarkus Show" played on KNAC in Boston. It led to a call from Eddie Cantor who invited Einstein to appear on his radio show.

Einstein moved to Hollywood, and in 1936 signed a movie contract with RKO. He wrote for the "Amos 'n Andy Show" and the "Pete Smith Specialties." (a favorite of this author) In 1941 he started a weekly radio show "Meet Me at Parky's." He retired in 1948. He came out of retirement for one performance in 1958 and died shortly afterward in Hollywood, California.

Einstein collected coins during the late 30's and devoted his retirement years to his collection and investments. His collection was sold at auction by Bowers and Merena June 23-25, 1986. The sale included an 1804 dollar. However, it was not from the Einstein collection.
