[b] Frank served as team president of the Baltimore Orioles of the American League in 1901, their inaugural season.

[2] John Mahon was elected to succeed Frank as chairman at the annual stockholders' meeting in February 1902.

[3] Outside of baseball, Frank managed the brokerage firm of Arthur Lipper & Company, and his business obligations were cited as the reason that he did not continue as president of the Orioles.

[3][4] When Mahon sold his controlling interest in the Orioles to John T. Brush and Andrew Freedman of the National League, Ban Johnson, president of the American League, joined with Frank and other minority owners of the Orioles to seize control of the team.

[7] Following Frank's sale of his interest in the Orioles, there would not be another Jewish owner in the American League for nearly a half-century, until former player Hank Greenberg took an ownership position in the Cleveland Indians in 1949.
