Abbegasse (Breitensee) was named in 1930 after Ernst Abbe. 

Ernst Abbe (1850 – 1905) was a German physicist, optical scientist, entrepreneur, and social reformer. Together with Otto Schott and Carl Zeiss, he laid the foundation of modern optics. Abbe developed numerous optical instruments. He was a co-owner of Carl Zeiss AG, a German manufacturer of research microscopes, astronomical telescopes, planetariums and other optical systems. Abbe established the Zeiss foundation in 1889. The foundations charter of 1896 showed Abbe‘s social commitment. For example, employees had co-determination rights, paid vacation, profit-sharing, a documented right to retirement pay, continued payment of wages in the event of illness, and starting in 1900, an eight-hour workday.
