Godfrey Henschen (also Henskens or Henschenius in Latin), 21 June 1601 – 11 September 1681, was a Belgian Jesuit hagiographer, one of the first Bollandists.
Henschen was born at Venray, Limburg, in the Low countries. He was the son of Henry Henschen, a cloth merchant, and Sibylla Pauwels. He studied the humanities at the Jesuit college of Bois-le-Duc (today the town of 's-Hertogenbosch) and entered the novitiate of the Society of Jesus at Mechlin on 22 October 1619. He taught successively Greek, poetry and rhetoric at Bergues, Bailleul, Ypres, and Ghent. He was ordained a priest on 16 April 1634, sent to the professed house at Antwerp the following year, and admitted to the profession of the four Jesuit vows on 12 May 1636.
Henschen had been a pupil of Jean Bolland. From the time of his arrival in the city he was associated as a collaborator with Bolland, who was then preparing the first volumes of the Acta Sanctorum. Bolland had asked for an assistant, a request supported by the abbot of Liessies Abbey, Antoine de Wynghe. In 1635 Henschen was assigned to start work on the February saints, while Bolland gave himself to the preparing the material for January. It was Henschen who, by his commentary on the Acts of St. Amand, suggested to Bolland the course to follow, and gave to the work undertaken by his mentor its definitive form. After fourteen years of work, the two volumes for January were printed in Antwerp in 1643 and greeted with enthusiasm by scholars.
