Gustava

Gustava Kahler, née Aigner, (1906 – 1987) was an Austrian geologist and palaeontologist. She was noted in particular for her work with Franz Heritsch and with her husband, Franz Kahler. In recognition of her discovery of graptolites in the northern greywacke zone, her former fellow student, Ida Peltzmann, named two species for her.

She studied geology, paleontology, mineralogy and petrography at the University of Graz. She was only the second woman to study geology at an Austrian university. She earned her PhD in July 1929, when she was only 23 years old, with a dissertation entitled "Die Productiden des Karbons von Nötsch I'm Gailtal". Her dissertation was the first to reflect a redirection of study in the field away from mineralogy and crystallography and towards stratigraphy and palaeontology.

Gustava Johanna Stenborg (1776–1819) was a Swedish artist.
