P. J. Haaxman

P. J. Haaxman is a scarce figure in the historical record, but he is credited as the author of Antonie van Leeuwenhoek: de ontdekker der infusoriën, 1675-1875, published in 1875. Modern library and catalog records, including Project Gutenberg, Open Library, and the Biodiversity Heritage Library, preserve that title and keep his name in circulation.

A specialist site on Leeuwenhoek’s biographers identifies Haaxman as an apothecary living in Rotterdam and describes his book as the first full-scale biography of Leeuwenhoek. That makes his work noteworthy not just as a period publication, but as an early attempt to tell the story of one of science history’s most famous microscopists.

Very little else about Haaxman has been easy to confirm from reliable online sources, which adds to the sense of him as a half-hidden 19th-century author whose reputation rests mainly on a single enduring book. For readers interested in the history of science, that alone gives his writing a distinctive place.
