Lee Daniel Crocker (born in Valdosta, Georgia on July 3, 1963) is an American computer programmer and poker player. He is best known for rewriting the software upon which Wikipedia runs to address scalability problems. This new software, originally known as "Phase III", went live in July 2002 and became the foundation of what is now called MediaWiki. Today, MediaWiki's Subversion code repository is still named "phase3".
He was involved in the creation of the GIF, JPEG, and PNG image file formats, and appears as a co-author of the PNG specification. He invented the per-scanline variable pre-filtering compression method used by PNG, the sum-of-abs heuristic used by many encoding programs, and proposed an early version of the Adam7 algorithm, using 5 passes rather than 7.
In June 2010, Crocker and others won the USENIX Advanced Computing Technical Association STUG award for contributions to the Wikipedia software.

Famous quotes containing the words lee, daniel and/or crocker:
“That’s playgirl stuff, Brownie. I’ve seen them in London, Paris, Rome. They start life in a New York nightclub and end up covering the world like a paid advertisement. Not an honest feeling from her kneecap to her neck.”
—John Lee Mahin (1902–1984)
“Fair is my Love, and cruel as she’s fair
Her brow shades frowns, although her eyes are sunny;
Her smiles are lightning, though her pride despair;
And her disdains are gall, her favours honey.
A modest maid, decked with a blush of honour,
Whose feet do tread green paths of youth and love,”
—Samuel Daniel (1562–1619)
“For some people, their idea of getting tough is longer suspended sentences.”
—Jeremy Larner, U.S. screenwriter. Senator Crocker Jarman (Don Porter)
