A noted probate attorney, Mac died April 2, 2023, in Bloomington, Minn. 

Son of McNeil V. Seymour 1919 and Katherine Klein Seymour, he came to Princeton from St. Paul Academy. He also had three uncles who attended Princeton. At college he ran on the freshman track team and played 150-pound football for four years. He majored in A.C.P. English and was a member of Quadrangle Club and Whig-Clio. During senior year he roomed with Barry Veret.

Following Princeton, Mac graduated from the University of Chicago Law School and then served on active duty in the Army, as a “six-monther,” a reservist, and later on active duty again during the Berlin crisis. When not on active duty, he joined his father’s law practice, forming the firm of Seymour & Seymour. He and his father represented the First National Bank of St. Paul and also argued numerous probate cases before the Minnesota Supreme Court. In 1961, he married Alice Forsythe, and they had four children: Margaret, McNeil III, James, and Benjamin. After his father died, Mac joined the larger firm of Briggs & Morgan, specializing in estate and trust matters. He also became a director of various business firms and charities in the Twin Cities area. 

After Alice died, Mac was a single parent for a while, and his children remember having received letters from him at their summer camp that they characterized as “legal briefs.” Eventually he married Mary, and gained four stepchildren. 

Mary, his four children and four stepchildren, and their families survive him.
