He first studied at the university in his hometown from 1883 to 1884, and then moved to Berlin for one semester before returning in 1886 to Freiburg. He wrote his thesis at Berlin, on the Lauraceae (the Laurel family), and received his Doctor of Philosophy from there.

His main areas of research were systematics and physiology.
He continued to study the taxonomy and morphology of the Lauraceae, and introduced the use of serology as a method of studying plant relationships. Also, he studied mycology, and wrote about dry rot. The plant genera Mezia Schwacke ex Niedenzu and Meziella Schindler, were named in his honor.
