The Lucasian professor is the holder of a mathematical professorship at Cambridge University. The post was founded in 1663 by Henry Lucas[?], who was Cambridge University's representative to Parliament in 1639-1640. Lucas, in his will, bequeathed his library of 4,000 volumes to the University and left instruction for the purchase of land whose yielding would provide £100 a year for the founding of a professorship. In 1860, the fund had risen to only £155.
