Jacques Millot (9 July 1897, Beauvais – 23 January 1980, Paris)[1] was a French arachnologist, who also made significant contributions in the fields of ichthyology and ethnology.

He studied histology under Justin Marie Jolly at the Collège de France in Paris,[2] earning his medical doctorate in 1922.

In 1931 he became a professor of physiological anthropology, and in 1943, he was appointed chair of comparative anatomy at the Muséum national d’Histoire naturelle, a position he kept up until 1960.

In 1947 he was named director of the Institut scientifique de Madagasgar, and during the following year, became president of the Académie malgache (Malagasy Academy).

[3] He is best known for his anatomical and histophysiological investigations of arachnids, that included intensive studies involving the silk glands of the genus Scytodes (spitting spiders).
