Alfred Ernst, c. 1935

Alfred Ernst (21 February 1875, Winterthur – 17 September 1968, Zürich) was a Swiss botanist.

He attended classes at the teachers' seminar in Küsnacht, followed by studies of biological sciences in Paris. From 1897 to 1899 he worked as a teacher in Naples. Afterwards, he received his doctorate in sciences from the University of Zürich, where in 1905, he became an associate professor. From 1909 to 1945 he was a professor of general botany at Zürich, being chosen university rector in 1928.[1]

His primary research dealt with the propagation of algae, the embryology of flowering plants and heterostyly in Primula species.[1] In 1905/06 and 1930/31 he was involved in botanical investigations in Java.[2]
