Horst Ludwig Störmer (born April 6, 1949) is a Bell Labs physicist who shared the 1998 Nobel Prize in Physics with Daniel Tsui and Robert Laughlin. The three shared the prize "for their discovery of a new form of quantum fluid with fractionally charged excitations" (the fractional quantum Hall effect). Störmer is currently a professor at Columbia University in New York.
