Schilder, F.A.
Franz Alfred Schilder was born in 1896. He published his first paper on Cowries in 1922 and continued to do so until 1971 (often together with his wife Maria). Almost 300 papers on Cypraeacea were published by this unique team describing more than 500 new taxa on the generic, specific and subspecific level. In addition he wrote several extensive papers on the variability of the landsnails Cepaea nemoralis and C. hortensis.
