In the first half of last century, people nicknamed "Dutch" were not Dutch at all...they were German. Dutch is the Americanized version of "Deutsch." The most famous Dutch to play for the Cubs was Dutch Leonard. His real name was Emil John Leonard, and he spent the last four seasons (1949-1953) of his impressive career as a reliever for the Cubs. In 1951, he even made the all-star team. (He was a four-time all-star as a starting pitcher during the War, while pitching for the Washington Senators). After he retired as an active player in 1953 (he was 44 years old at the time—the oldest player in the league), he became the Cubs pitching coach for three seasons.

Bonus Dutch Dutch Leonard was preceded on the Cubs roster by another Dutch--Dutch McCall. McCall pitched one full season in the majors (1948), and of course, it was for the Cubs. McCall was among the league leaders in several categories, most notably walks and losses. In fact, he set the Cubs record by recording 13 losses in a row. He also led the Cubs in home runs allowed, and the Cubs starters in highest ERA...and he was their #3 starter. The Cubs finished 27 ½ games out of first place that year, in dead last.
