Sir Maurice Alberic Twisleton-Wykeham-Fiennes, (1907-1994), played an important part in Sheffield’s industrial history. He is forgotten, but his grandchildren are most certainly not.
Fiennes was the son of Alberic Arthur Twisleton-Wykeham-Fiennes, and great-grandson of Frederick Benjamin Twisleton-Wykeham-Fiennes, 16th Baron Saye and Sele.
He was born at Brentford, educated at Repton, Derbyshire, and Newcastle-upon-Tyne, and in 1937 joined the United Steel Companies of Sheffield, taking charge of the forging and gun departments at Steel, Peech and Tozer. After a spell in Loughborough, Fiennes became Managing Director of Davy United Engineering at Darnall in 1945. He became Chairman of Davy-Ashmore, was knighted in 1965, and achieved success as a producer of high quality British steel until 1969.

Amongst his other roles, Fiennes was a President of the Iron and Steel Institute, Chairman of the Steel Works Plant Association, was on the Committee on Overseas Credit of the Federation of British Industries, and a member of the Engineering Advisory Council of the Board of Trade. Locally, he was President of the Sheffield and District Engineering Trades Employers Association, an Assistant on the Cutlers’ Company, and Chairman of the Committee of the Sheffield Philharmonic Society.
He married Sylvia Finlay in 1932 and had five children – three girls and two boys – the oldest of which was Mark Twisleton-Wykeham-Fiennes (1933-2004), a photographer and illustrator, chiefly known for his architectural photographs, which appeared in Country Life.

Mark Fiennes (third cousin to explorer Sir Ranulph Fiennes) married novelist Jennifer Lash in 1962 and had six children: Ralph, Martha, Magnus, Sophie, Jacob, and Joseph. They also fostered the 11-year-old Mike Emery.
Martha and Sophie are both film producers and directors, with Martha winning awards for her film Onegin and Sophie being director of arts documentaries. Magnus is a film and television composer whose work includes his sister’s Onegin and Chromophobia as well as television programmes like Hustle, Murphy’s Law, and Death in Paradise, and has also worked with Shakira, Pulp, Tom Jones and Morcheeba.
The two most famous of Mark and Jennifer’s children are Ralph and Joseph, acclaimed movie actors.
Ralph’s breakout role occurred in Schindler’s List, when he played Nazi concentration camp commandant Amon Göth. He’s since been in The Avengers, The English Patient, Red Dragon, and Voldemort in the Harry Potter series.
Joseph is no pale shadow, known best as William Shakespeare in Shakespeare in Love, as well as Elizabeth, Enemy at the Gates, Luther, The Merchant of Venice, and most recently in The Handmaid’s Tale. He also starred as Edward II at the Crucible Theatre in 2001.
Joseph’s twin brother, Jacob, is Director of Conservation at the Holkham estate in Norfolk, and foster brother Michael Emery is an acclaimed archaeologist.
