Professor Sir Colin John Humphreys, CBE (born 24 May 1941) is a British physicist. He is the former Goldsmiths’ Professor of Materials Science and a current Director of Research at Cambridge University, Professor of Experimental Physics at the Royal Institution in London and a Fellow of Selwyn College, Cambridge. He was President of the Institute of Materials, Minerals and Mining in 2002 and 2003. His research interests include "all aspects of electron microscopy and analysis, semiconductors (particularly gallium nitride), ultra-high temperature aerospace materials and superconductors."
Humphreys was awarded the A. A. Griffith Medal and Prize in 2001 and a CBE in 2003 for services to science as a researcher and communicator. He was knighted in the 2010 Birthday Honours and in 2011 elected a Fellow of the Royal Society  He is also mentioned in Debrett's People of Today.
Biblical study and publications
In 2011 Humphreys claimed in his book The Mystery of the Last Supper that the Last Supper took place on Wednesday (Holy Wednesday), not as traditionally thought Thursday (Maundy Thursday), and the apparent timing discrepancies (Nisan 15 or 14) between the gospels of Matthew, Mark, and Luke versus John are rooted in the use of different calendars by the writers, the former group using an older Jewish calendar and the latter a lunar calendar. The Last Supper being on Wednesday would allow more time for interrogation and presentation to Pilate prior to the cruxification than given in the traditional view. Humphreys proposed the actual date for the Last Supper to be 1 April 33.

"The new study is based on earlier research which Professor Humphreys carried out with the Oxford astrophysicist, Graeme Waddington, in 1983. This identified the date of Jesus’ crucifixion as the morning of Friday, April 3rd, AD 33 – which has since been widely accepted by other scholars as well. For Professor Humphreys, who only studies the Bible when not pursuing his day-job as a materials scientist, this presented an opportunity to deal with the equally difficult issue of when (and how) Jesus’ Last Supper really took place."
