Jacobus Zegers (died 14 January 1644) was an academic printer and bookseller in Leuven, with many clients among the faculty of Leuven University. He was the printer of Cornelius Jansen's Augustinus (1640).
Zegers settled in Leuven around 1631, married twice, and had a thriving business as an academic publisher and bookseller. His clients included Nicolaus Vernulaeus and Diodorus Tuldenus.[1]
Having printed Cornelius Jansen's massive three-volume Augustinus in 1640, the papal condemnation of the work and the ensuing controversies drove Zegers to the brink of bankruptcy and led to his untimely death. His widow continued the bookshop, with the support of Jansenist patrons.
