Pieter van der Hoog

Pieter Henricus van der Hoog, also known after converting to Islam as Mohammed Abdul-Ali, was a Dutch bacteriologist, dermatologist, and Islamicist. Born in The Hague, Van der Hoog was pressured by his father to enter the Dutch military, for which he served as a doctor. During his time with the Royal Netherlands East Indies Army in the Dutch East Indies from 1913 through 1921, he practised in several areas but was censured and arrested. Returning to the Netherlands, he earned a doctoral degree from the University of Leiden in 1922. After some time practising medicine in the Netherlands, in 1926 he was sent to Curaçao; he was ultimately blacklisted by the Ministry of the Colonies for his continued attacks on the Governor of the Netherlands Antilles.
