Professor He Zehui or Ho Zah-wei (Chinese: 何泽慧; March 5, 1914 – June 20, 2011) was a Chinese nuclear physicist who worked to develop and exploit nuclear physics in Europe and China.

He Zehui was born in Suzhou in 1914. She attended Suzhou No.10 Middle School where she was interested in a variety of subjects and she was on the volleyball team. She graduated from Tsinghua University in Beijing in 1936, with a degree in physics. She then went on to study at the Technical University of Berlin, where she was the top student in her class, outperforming her future husband Qian Sanqiang as well.

She was sent to Germany because the Germans were interested in high technology ordnance. She earned a Ph.D in Engineering in 1940 with her thesis that dealt with a new way of measuring the speed of high velocity bullets. She studied nuclear physics for several years in Germany working for Siemens before joining the Kaiser Wilhelm Institute (now the Max Planck Institute for Medical Research) in Heidelberg in 1943.Friedrich Paschen who had been her landlord in Germany, and later an adopted parent, introduced her to Walther Bothe, who had just built the first German cyclotron. With Bothe's assistance she studied radioactive particles and cosmic rays, and she worked on Heinz Maier-Leibnitz's cloud chamber technology.
