Veit is renowned for adapting the knowledge of immunology into the field of gynecology.
He was successful in treatment of cancer with radium, and was involved in training nurses and midwives for service in the German colonies and diaconal hospitals in the Middle East.
[1] During his tenure in Berlin, Veit worked closely with Carl Arnold Ruge (1846-1926) in establishing gynecological histopathology standards, particularly involving the setup of microscopic diagnostics for early detection and analysis of uterus carcinomas.
His written works included publications on female reproductive anatomy, gynecological diseases and ectopic pregnancy.
With Robert von Olshausen (1835-1915), he was co-editor of Karl Schroeder's Lehrbuch der Geburshülfte.
