Eugene Gressman was born April 18, 1917 in Lansing, Michigan. He graduated from the University of Michigan (A.B., 1938; J.D., 1940). After his admission to the Michigan Bar in 1940, Gressman worked as an attorney with the Securities and Exchange Commission in Washington, 1940-1943. From here, he became law clerk to Supreme Court Justice Frank Murphy, serving from 1943 to 1948. Following Murphy's death, Gressman worked with different Washington law firms.
As a result of his work with Frank Murphy, Gressman became a national authority on practice and procedure before the United States Supreme Court. He was both a writer and teacher on the law. He co-authored the leading lawyers guide to Supreme Court practice and procedure entitled Supreme Court Practice. He has also written articles and pamphlets on the topic, as well as on other federal constitutional and statutory issues. In addition, he has co-authored a constitutional law textbook, and authored part of a treatise on federal jurisdiction. As professor, he has taught courses in constitutional law, federal jurisdiction, professional responsibility and seminars in Supreme Court practice. He has taught some or all of these courses at the North Carolina, Seton Hall, Fordham, Michigan, Ohio State, Indiana at Indianapolis, Catholic and George Washington University law schools.
