He was born in Montclair, N.J., on Sept.. 30, 1927, the son of Brantz M. and Marjorie Hanan Bryan.

He was educated at the Millbrook School in Millbrook, N.Y., graduating in 1946. Mr. Bryan was a fourth generation Princetonian where he earned a bachelor of arts degree in 1952, majoring in politics and history. At Princeton he was a member of the Tower Club.

Prior to Princeton he enlisted in the U.S. Army and served as a sergeant during the occupation of Japan.

He enjoyed a 54-year business career, the first 18 of which were spent as a management professional with major marketing and advertising agencies, both in New York and Hollywood, such as Doyle Dane Bernbach, Ted Bates, D’Arcy and Erwin Wasey.

He was a vice president in charge of creating several of America’s best known and loved ads for Alka Seltzer, Gillette super stainless, Palmolive Rapid Shave, Colgate toothpaste and Friskies dog and cat foods.
