Maurice Edwin Tucker (born 6 November 1946) is a British sedimentologist, specialising in the field of carbonate sedimentology, more commonly known as limestones.
Tucker's research interests focus on the properties of sedimentary rocks, particularly limestones, their formation and usefulness as an oil reservoir.
Maurice Tucker was Master of University College, Durham from 1998 to 2011, and in the last formal dinner of the Easter Term 2010 his portrait by Andrew Ratcliffe was unveiled, to be hung in the Great Hall.
The portrait features a fossil that he found at the age of 7 in the family back garden at Newbury Park, which began his fascination with geology.
While Master, he inhabited the entirety of the large house at the base of the Keep, along with his wife – regularly entertaining students in his garden in the summer months.
