Louis Corstorphine Peringuey, also known as Louis Gaston, was the son of Louis Albert Peringuey*, director of the South African Museum, Cape Town, and his wife Bertha Marcellis. His second given name (Corstorphine) was presumably bestowed upon him in honour of a friend of his father, the geologist George S. Corstorphine*.
As a young boy Peringuey junior donated insects to the South African Museum during 1907 to 1909. In the latter year his father wrote in the museum's annual report: "Master Peringuey has assiduously collected the micro-coleoptera of the [Cape] Peninsula and has been very successful in obtaining numerous and rare kinds".
Peringuey qualified as a medical practitioner and settled in the Transvaal. He was married to Barbara Wells-Jones, with whom he had three surviving children.
