Samuel Iperuszoon, Knight Wiselius (4 February 1769 – 15 May 1845) was a successful Dutch lawyer and a prominent Patriot and democrat, involved in the dismantling of the Dutch East India Company (VOC) and the negotiations over the Cape. Wiselius was a witty, Voltairian spirit with political views far ahead of his time who would end his days writing dramas on Classical themes. Wiselius corresponded with nearly all the main players at the time of the Batavian Republic and it would be impossible to know that period completely without his carefully kept and neatly written correspondence. He was also a poet, historian and superintendent of the police.
