Franziska Seidl (née Vicari; 1 July 1892 – 14 June 1983) was an Austrian physicist. She was professor for experimental physics at the University of Vienna. One of her main research areas was ultrasound.

Biography

Franziska was born in

Isonzo Front.[1][2]

After the

doctoral thesis on measuring short time intervals with the Helmholtz pendulum, and earned her doctorate in physics in 1923.[1][2]

Seidl became assistant professor in 1924 and qualified as a professor for experimental physics in 1933. She took over as interim head of the First Physics Institute in 1945 until Felix Ehrenhaft returned from emigration in 1947. She became emeritus in 1963.[1][2]

Starting in 1933, Seidl regularly held lectures and supervised students' courses and doctoral theses. A main focus of her work was the education and training of physics teachers. From 1946 to 1967, she was president of the Austrian association for the promotion of physical and chemical education. In this function she organised in-service training weeks for teachers, notably an international event in 1960.[1][2]

Having been educated in music, her research initially focused on acoustics before she turned to ultrasound, X-ray crystallography, acousto-optics, and piezoelectricity of crystals. She also invented and patented a diaphragm-less crystal telephone. Her work on ultrasound contributed to today's applications in medicine and ultrasonic testing of materials.[1][2]

For her work she was given the Decoration of Honour for Services to the Republic of Austria in 1968.[2]
