In 1908, his father Solomon, after serving in the Austrian army, moved his wife and six year old Solly to New York's Lower East Side.

[1] Fighting as a featherweight in his professional debut on February 25, 1919, he aggressively won over veteran boxer Bobby Dobbs in the Manhattan Casino on November 29, 1921.

He may have overtrained for his final tournament bout with French boxer Benny Valgar, and lost in a close ten-round decision in Queensboro Stadium on May 18, 1925.

The Milwaukee Journal praised Goodrich's superior defensive skills and summarized the fight when they wrote, "Seeman's cleverness helped him to hold command throughout."

He won a bout with Young Leonard by second-round TKO in the Garden on March 26, 1926, but his dominance in the Lightweight division began to fade afterward.
