Joachim Ottens (1663 - 1719) and his sons Renier and Joshua were prominent Dutch booksellers and map publishers from about 1680 to 1790. Joachim, the founder of the firm, was initially employed as a copperplate engraver by Frederick de Wit. In 1711 Joachim founded his own firm. Though Joachim died only a few years later, his sons Renier and Joshua took over the firm and presided over its most prolific period.
