Regnerus Praedinius

Regnerus Praedinius or Reinier Veldman (1510 – 1559) was a Dutch humanist, rector, reformer, and teacher.

Johannes Acronius Frisius, Volcher Coiter, and Abel Eppens were among his students.

He studied theology at the Fraterhuis in Groningen, and at Leuven, before becoming the rector of the St. Maartens school.

He began to find problems in the Catholic Church and sought to reform the system.

Reinier was likewise altered through the word "regnare" (to govern) to Regnerus.
