Life

Franz Boll was born as the fourth of six children and the only surviving father of the pastor and historian Franz Boll's son in the south-east Mecklenburg Vorderstadt Neubrandenburg. Initially tutored by his father himself, he received an excellent education and later attended the Neubrandenburg high school, where he passed the Abitur at Easter 1866. From 1866 Boll studied medicine at the universities of Bonn , Heidelberg and Berlin . As a student with Max Schultze in Bonn , he published several histological works. In 1869 he received his doctorate in Berlin . In the following year he passed the state examination and received a position as an assistant in the physiological institute of Emil Heinrich Du Bois-Reymond .

For health reasons, Boll tried to get a job in Italy. After he had unsuccessfully applied for a professorship in Genoa , he unexpectedly received a chair for anatomy and comparative physiology in Rome in 1873 . There he published in both German and Italian. His discovery of the visual purple formed the basis for further research. Connected with his name are the Boll cells , also called Boll cells , which are basket cells in the lacrimal gland .

Franz Boll was married to Margarete Traube (1856–1912), daughter of the Berlin doctor Dr. med. Ludwig grape . The short marriage remained childless. His widow married Professor Gugliemo Mengarini in Rome in 1885 . With Boll's death, the male line of his family branch, which had produced great scholars for three successive generations, was extinguished.
