Jacob Aertz Calom (or Colom), b. 10 October 1599 at Dordrecht, d. 10 May 1678 at Amsterdam, was baptized in the Amsterdam Waterlander congregation, 25 September 1622, and remained a member of this congregation until his death. He was a bookseller and published among others a large number of Mennonite books. In the dispute in the Waterlander congregation about the charge of Socinianism made against Nittert Obbes, Calom published a pamphlet in Obbes' defense, titled Antwoord op seeckere drie vragen, of which he was probably the author. At least one of his daughters was a member of the Waterlander congregation, but all of his sons joined the Reformed Church.
Calom was very expert in matters of mathematics and navigation; he wrote various cartographic books, and besides these technical works: Troost der Zeevaart (Comfort of Navigation) (Amsterdam, 1651) and Onderrigting in de Konst der Zeevaart (Instruction in the Art of Navigation). vdZ.
