Charles Wilhelm Heitkamp (March 21, 1822 - June 1, 1875) was a German-American merchant, lawyer, and real estate investor based in East New York, Brooklyn, in the mid to late 19th century. Heitkamp was born in Alzey, Alzey-Worms, Rhineland-Palatinate, Germany. He was an early settler and promoter of that portion of New Lots, Brooklyn, that is now known as East New York. It is not clear when he emigrated to the Untied States, but he was likely a 48er - one of the multitude of educated Germans that fled the Fatherland in the wake of the failed 1848-49 Springtime of the Peoples Revolutions.
