The Batavian Society of Experimental Philosophy (= experimental science) is one of the oldest scientific societies in the Netherlands. Founded in 1769 in Rotterdam by Steven Hoogendijk: a wealthy clockmaker. Probably modeled on the Accademia dei Lincei (1603-1651) and the Royal Society (1660-present). While the first century and a half of its existence mainly promoted various forms of technical innovation, in the past century the emphasis shifted to both medicine and technology. The society had its own laboratory and an extensive arsenal of historical scientific instruments, as well as an extensive historical innovation library. Unfortunately, most of these possessions were lost in the bombing of Rotterdam in May 1940.
