Rauschenberg was born in Bremen in 1853 and attended the local secondary school. After studying architecture, he opened offices in his home town offering designs in the Neo-Renaissance style. In 1891, he and Wilhelm Martens saw the completion of the Historicist styled Deutsche Bank building in Bremen.[1]
In 1893, he spent a decade away, first in Munich and then in Karlsruhe. He returned in 1903 and set up in partnership, creating designs more in the Art Nouveau style.
Rauschenberg died in Bremen.
