Born in Hamilton, Ohio, James Isaminger, began his career in journalism with the Cincinnati Times-Star. Recommended by American League founder and president Ban Johnson, Isaminger joined the staff of the Philadelphia North American in 1905. When the paper folded in 1925, Isaminger moved to the Philadelphia Inquirer where he penned his well-known columns "Tips from the Sporting Ticker" and "Under the Spotlight."
The longtime editor and co-author of the Reach annual baseball guides, Isaminger was a Philadelphia institution. His investigative efforts, along with those of Ring Lardner and Hugh Fullerton, were instrumental in exposing the truth behind the "Black Sox" scandal of 1919.
A former president of the Baseball Writers' Association of America, Isaminger died in 1946 at the age of 65.
