Zacharias Janssen; also Zacharias Jansen or Sacharias Jansen; 1585 – pre-1632[1]) was a Dutch spectacle-maker who lived most of his life in Middelburg. He is associated with the invention of the first optical telescope and/or the first truly compound microscope, but these claims (made 20 years after his death) may be fabrications put forward by his son.
