Gerda Laski (4 June 1893, Vienna – 24 November 1928, Berlin) was an Austrian/German physicist known for her research in infrared radiation. She went to the private girls' secondary grammar school of Vienna and graduated in 1913

She earned her doctorate under prof Ehrenhaft in physics from the University of Vienna in 1917 on "Size determination of submicroscopic particles from optical and mechanical effects". From 1918-1919 she worked as an assistant at the University of Gottingen and in 1920 at the University of Berlin.

Laski directed the Kaiser Wilhelm Society's Institute for Fibers Research as the department head from 1924 before moving to the Physikalisch-Technische Bundesanstalt (Physical-Technical Imperial Institute) to start her own department in 1928. Her research concerned the Bohr model.[1][2] Laski was Peter Debey's student a noble prize winner. Deby studied the dispersion of light by Bohr's hydrogen model and found that theoretical curve fitted the observed one satisfactorily. Then, Gerda Lski showed agreement between theory and experiment.

Liska became an assistant in the physics institute of the university of Berlin, where, she was introduced to the experimental technique that became her major interest. The Kaiser Wilhelm Institute for Physics gave Laski a monthly scholarship until her death which was due to a serious illness and occurred very soon after she started working there. She died in Berlin on November 24, 1928.

Lisa's first publication was a book about submicroscopic particles. Her last work was "special methods for measurement in the infra-red" and "Thermoelectricity".Also. she contributed to the article on infra-red research (1924) of the "Ergebnisse der extraction"

Her research included studying infra red natural frequencies of diatomic Bohr gas molecules and their specific heat at high temperatures.
