David Klein (1908 – 1993) was a Swiss human geneticist and ophthalmologist.
He moved to Geneva as scientific assistant to professor Adolphe Franceschetti at the ophthalmological clinic.
After retirement, he was active as consultant in human genetics at the ophthalmological clinic, Geneva, and the school of amblyopic and blind children in Baar, Switzerland.
In August 1947 Klein presented a deaf mute child, who was 10 years of age, and had partial albinism of the hair and body, blue hypoplastic irides, blepharophimosis and malformation of arms, to the Swiss Society of Genetics, and gave a full report of his findings in 1950.
