He specialized in the popular extreme long-distance races of the beginning of the 20th century. In 1902 he won the first Corsa del XX Settembre, a 460 km race between the cities of Rome and Naples organised to commemorate the Italian reunification.

He was born in Christophstal, a small hamlet near Freudenstadt, in Württemberg. At a young age he moved to Rome where he was active in the family business. He remained in Rome until his death.
