James E. "Grasshopper" Whitney. Pitcher with the Washington Nationals in 1887-1888. In 1881, Whitney's 31-33 record led the league in both wins and losses; 31 wins still stands as the MLB record for wins and a losing record. He died in 1891 of tuberculosis at the age of 33.
(Note that the flip identifies Art Whitney, who was an active MLB player in the era, but never for Washington. Jim Whitney, on the other hand, played for Washington in 1887-1888. The picture on the card is generic.)
