In 1890, in the year that David Sidelman was born, on December 29th, the Wounded Knee Massacre occurred in South Dakota on the Lakota Pine Ridge Indian Reservation . The U.S. 7th Cavalry Regiment said that they rode into the Lakota camp "trying to disarm" the inhabitants. One person, Black Coyote - who was deaf - held onto his rifle, saying that he paid a lot of money for it. Shots rang out and by the end at least 153 Lakota Sioux - some estimates say 300 - and 25 troops had died. The site of the massacre is a National Historic Landmark.

In December, he introduced a paper on the Planck postulate which stated that E=hv - the energy of a photon is proportional to its frequency times a constant. Planck won a Nobel Prize in 1918 for his work in theoretical Physics.
