19th-century Belgian Roman Catholic priests

Jean Baptiste Carnoy (11 January 1836 – 6 September 1899), born in Rumillies (Belgium), was a Roman Catholic priest and a scientist in the field of cytology. He made the initial explanation of the real nature of the albuminoid membrane, and conducted noted experiments on cellular segmentation.

Theophile Meerschaert (24 August 1847 – 21 February 1924) was a Belgian-born prelate of the Catholic Church. He served as the Bishop of the Diocese of Oklahoma (and its predecessor) in the United States from 1891 until his death in 1924.
