Lewis Pessano "Buttercup" Dickerson (October 11, 1858 – July 23, 1920) was a 19th-century Major League Baseball outfielder. Born in Tyaskin, Maryland, he played a total of seven seasons in the majors, splitting time between eight teams in three different leagues. He is credited by the National Italian American Sports Hall of Fame as the first Italian-American to play in the majors, but conversations with family members have called into question whether the family has any Italian ancestry.
