Life

Bachmann's father was a professor of physical chemistry at the Technikum Winterthur (today: Zurich University of Applied Sciences). He studied agricultural engineering at the Swiss Federal Institute of Technology in Zurich (ETH Zurich) from 1942 to 1947 and received his doctorate there in 1953. Since 1947, he has been researching the yellow fruit tree scale at the Federal Research Institute for Fruit, Viticulture and Horticulture in Wädenswil , in which he first described a new species for the genus Quadraspidiotus, the Quadraspidiotus schneideri n. sp, named after him as Quadraspidiotus schneideri  Bachmann. He also worked on the scale insect fauna in Southeastern Europe and on the history of viticulture in Switzerland. He was also active in industrial plant protection in Basel and politically in the development of the regional ring of the independents .
