Theodore Levin (February 18, 1897 – December 31, 1970) was a prominent immigration lawyer and United States federal judge who served on the U.S. District Court for the Eastern District of Michigan from 1946 until his death in 1970.
Levin was born in Chicago, Illinois, though his family lived in London, Ontario Canada, from 1905 to 1913. After that, Joseph and Ida Levin brought their eight children back to the United States and settled in Detroit, Michigan. Levin received a LL.B. from University of Detroit School of Law in 1920, and an LL.M. from the same institution in 1924. He was in private practice of law with his brother Saul in Detroit from 1920 to 1946.
In the 1930s, Levin was part of a group of immigration lawyers who opposed the Michigan Alien Registration and Fingerprinting Act. He was a member of the executive board of the National Refugees Service Administration and an officer of the Michigan Commission on Displaced Persons.
In 1933, Levin was appointed special assistant attorney general in an investigation into the Michigan Bank Holiday and from 1944 to 1946, he served as a member of the Selective Service Appeal Board.
On July 3, 1946, Levin was nominated by President Harry S. Truman to a seat on the United States District Court for the Eastern District of Michigan vacated by Edward Julien Moinet. Levin was confirmed by the United States Senate on July 25, 1946, and received his commission on July 27, 1946. He served as chief judge of the court from 1959 to 1967, and thereafter served until his death.
