“The other Swiss writer was of a different character. He was a professor while Bürgi was a watchmaker; his name has been known for three centuries, while Bürgi’s has been almost forgotten; but he was a plagiarist, while Bürgi was a genius. {{w|Paul Guldin}} began his work as a goldsmith. He later entered the Jesuit order, lived for a long time in Rome, and became professor of mathematics at the {{w|University of Vienna}} and later at Gratz.”
