Hermann graduated from
New Brunswick High School in 1919 As a baseball player, he reportedly had a .472
batting average and, in 1921, was the highest-scoring
guard in
college basketball. He graduated from Colgate in June 1923, Within days, however,
Christy Mathewson, president of the Boston Braves, announced that Hermann had signed with the club. He was in uniform with the team at
Braves Field by June 28. He nearly made his debut on July 9 when third baseman
Tony Boeckel was ejected for kicking dirt on home plate umpire
Ernie Quigley. Hermann was sent out to third base to warm up before the next inning but manager
Fred Mitchell chose instead to substitute
Gus Felix. Hermann made his debut a few days later on July 11 against the
St. Louis Cardinals He recorded his first two
hits in a game at
Ebbets Field on July 22, both
singles against
Dutch Henry of the
Brooklyn Dodgers. In the same game, he also recorded his first two
runs batted in and his first
stolen base. Hermann stayed with the Braves for the remainder of the season, accumulating a .237/.237/.280
slash line. Within eight days of the end of the 1923 season, Hermann was reportedly on the sidelines coaching the Suffield football team in its season opener against the freshman team of
Tufts University. Hermann left Suffield in early March 1924 to join the Braves in
St. Petersburg, Florida for
spring training. He was one of several young infielders competing to fill the void left by the offseason death of Tony Boeckel. He made his season debut on April 20, 1924 at the
Polo Grounds against the
New York Giants. In a one-run game with two runners on base in the ninth inning, the Braves inserted
Earl Smith as a pinch hitter for
Mickey O'Neil against
Walt Huntzinger. However, when the Giants countered by substituting
Art Nehf to face Smith, the Braves swapped out Smith in favor of Hermann in order to regain the
platoon advantage. Nehf struck out Hermann and the following batter and the Braves lost. This would be Hermann's final game in the major leagues. Within days of his lone appearance of the 1924 Major League season, Hermann was
farmed out to the
New Haven Profs of the
Eastern League. Hermann reportedly found great success in his brief time in New Haven. In less than a month, the Braves had him moved to the Eastern League's
Worcester club where they could watch him more closely. During the 1924–1925 offseason, the Braves traded Hermann to the
Albany Senators of the Eastern League, for whom Hermann initially refused to play. He wanted to be given the opportunity to play in a classification higher than
Class A because, if he found he could not succeed at a higher level, he would quit baseball and begin a career using his college education instead. By that April, however, he left his coaching job at Suffield to end his
holdout and join the team and would continue to play for Class A teams for the next several years. In 1929, he played for the
Wichita Falls Spudders and, according to a columnist for the
Wichita Falls Times, would "be remembered for a long, long time as the worst third baseman in the history of the club." After the season, he was sold to a club in the lesser
New York–Penn League. He split the 1930 season, his last in minor league baseball, between
Elmira, New York and
Allentown, Pennsylvania. ==Political career==
