Jonas Daniel Meijer (15 September 1780 – 6 December 1834) was the first Jewish lawyer in the Netherlands. He has had a significant impact on Dutch law, and is also known for his battle for (legal) emancipation of the Dutch Jews.
The Jonas Daniel Meijerplein, a square in Amsterdam (where Meijer died), was named after him. Bordering the square are the Esnoga and four former synagogues, now together home of the Joods Historisch Museum (Jewish Historical Museum). The Dokwerker monument on Jonas Daniel Meijerplein commemorates the February strike of 1941, a general strike by many (non-Jewish) people of Amsterdam and surrounding cities after the arrest and deportation of 425 Jewish men from Amsterdam to Mauthausen and Buchenwald following a clash between Nazi police and two Jewish men a couple of days earlier.
