Martinus van Marum

Martin(us) van Marum (20 March 1750, Delft – 26 December 1837, Haarlem) was a Dutch physician, inventor, scientist and teacher, who studied medicine and philosophy in Groningen. Van Marum introduced modern chemistry in the Netherlands after the theories of Lavoisier, and several scientific applications for general use. He became famous for his demonstrations with instruments, most notable the Large electricity machine, to show statical electricity and chemical experiments while curator for the Teylers Museum.

He moved to Haarlem in 1776 because the Haarlemmers had more taste in the sciences than anywhere else in the Netherlands. After his arrival in Haarlem he began to practise medicine, but devoted himself mainly to lecturing on physical subjects and creating instruments to demonstrate physical theory. He must have made a big impression on Haarlem society, because he became a member of the Dutch Society of Science in the same year, but was named director and curator of their cabinet of curiosities in the next year. He received at first no salary, but by scaring off the former cabinet concierge Nicolaus Linder, he was able to collect Linder's' salary of 100 guilders, and when the cabinet moved later in 1777 to new quarters in the Grote Houtstraat 51, van Marum lived there as concierge. He managed to scare off Linder by obtaining permission from the society to allow his servants to keep tips they received from cabinet visitors; a source of income that Linder had come to rely on. Then van Marum increased this salary to 300 from 100 by adding responsibilities to his list of duties, such as a summer garden in the Rozenprieel and eliminating other expenses.

In 1779 he was entrusted with the care of the Second society left to Haarlem by Pieter Teyler van der Hulst (1702-1778), which led under his direction to the foundation of the Teylers Museum. The Teyler legacy was split into three societies, one for religion, one for science, and one for the arts, known as the first, second, and third societies. The caretakers had to meet in Teyler's home weekly, and each society had 5 caretakers, so all of the gentlemen involved lived in Haarlem. In 1794 van Marum became secretary as well as director of the Dutch Society of Science. Under his management, both societies were advanced to the position of the most noted in Europe. Period travelogues mention both Museums.
