"Gus" Bryngelson loved practicing law. He especially enjoyed serving on Bar Association committees and "his attendance at meetings, and his enthusiastic support of all the social events bore witness to this devotion." He died on January 25, 1956, at age 68. In memorial proceedings for the Hennepin County Bar Association, a colleague recalled:
"He possessed the ability for which most of us strive -- to impress the bench with his thorough knowledge of the law, and the jury with his thorough knowledge of people and human nature, and the his success in our profession is proof of his talents."
A memorial to his wife Beth Scott Bryngelson (1895- 1976) is in the 1977 Hennepin County Bar Memorials.
A memorial to their son R. Scott Bryngelson (1929-1992) is in the 1993 Hennepin County Bar Memorials.
