Covens & Mortier
as a firm existed between 1721-1778, taking over the business of Pierrre Mortier.
Johannes / Jean Covens and Cornelius Mortier were brothers- in- law following the former's marriage to Mortier's sister Agatha in 1721, when they also formally went in to partnership.

Under the Covens and Mortier imprint, Cornelius and Jean republished the works of the great 17th and early 18th century Dutch and French cartographers De L'Isle, Allard, Jansson, & De Wit. The firm would become one of the most prolific Dutch publishing concerns of the 18th century.
The company would pass down through the Covens family as Mortier had no children, changing the name to Covens & Zoon until Pieter Mortier IV a great grandson of the original founder joined the firm and saw the name restored to Mortier Covens & Zoon. ( See Koeman I p45).
