Sir Frank Crisp, 1st Baronet, (25 October 1843 – 29 April 1919) was an English lawyer, microscopist and officer of the Royal Microscopical Society, to which he donated furniture, books, instruments and work on technical publications.
He counted several foreign railroad companies and the Imperial Japanese Navy among his clients, and drew up the contract for the cutting of the Cullinan diamond.
Having been knighted on 16 December 1907,[5] Crisp was created a baronet on 5 February 1913 for services as legal advisor to the Liberal Party.
He wrote a tribute to Crisp called "Ballad of Sir Frankie Crisp (Let It Roll)", which appeared on the album All Things Must Pass and later provided part of the title for his 2009 career-spanning compilation Let It Roll: Songs by George Harrison.
(It is actually from Ring Out, Wild Bells, a section of the Tennyson poem In Memoriam A. H. H.) The lyrics and title of another Harrison track, "The Answer's at the End", were also inspired by the writings of Frank Crisp: "Scan not a friend with a microscopic glass / You know his faults, now let his foibles pass / Life is one long enigma, my friend / So read on, read on, the answer's at the end."
