Sir Herbert Nigel Gresley (19 June 1876 – 5 April 1941) was one of Britain's most famous steam locomotive engineers, who rose to become Chief Mechanical Engineer (CME) of the London and North Eastern Railway (LNER). He was the designer of some of the most famous steam locomotives in Britain, including the LNER Class A1 and LNER Class A4 4-6-2 Pacific engines. An A1, Flying Scotsman, was the first steam locomotive officially recorded over 100 mph in passenger service, and an A4, number 4468 Mallard, still holds the record for being the fastest steam locomotive in the world (126 mph).

Gresley's engines were considered elegant, both aesthetically and mechanically. His invention of a three-cylinder design with only two sets of Walschaerts valve gear, the Gresley conjugated valve gear, produced smooth running and power at lower cost than would have been achieved with a more conventional three sets of Walschaerts gear.

Gresley was born in Edinburgh (due to his mother's ante-natal complications), but was raised in Netherseal, Derbyshire, a member of the cadet branch of a family long seated at Gresley, Derbyshire. After attending school in Sussex and at Marlborough College, Gresley served his apprenticeship at the Crewe works of the London and North Western Railway, afterwards becoming a pupil under John Aspinall at Horwich of the Lancashire and Yorkshire Railway (L&YR). After several minor appointments with the L&YR he was made Outdoor Assistant in the Carriage and Wagon Department in 1901; in 1902 he was appointed Assistant Works Manager at Newton Heath depot, and Works Manager the following year.

S'Express (pronounced ess-express; sometimes spelled S'Xpress or S-Express; otherwise known as Victim of the Ghetto) were a British dance music act from the late 1980s, who had one of the earliest commercial successes in the acid house genre.

"Theme from S'Express", based on Rose Royce's "Is It Love You're After", was also one of the earliest recordings to capitalize on a resurgence of sampling culture and went to number one in the United Kingdom as well as the Hot Dance Club Play chart in the United States (also scraping into the U.S. Billboard Hot 100 at #91).

The main player in the act was DJ/producer and remixer Mark Moore. In 1989, the group released its debut album, Original Soundtrack, which featured a line-up of Mark M (Moore, noise engineer), Michellé (microdot clarinet and vox), Mark D (trumpet, noise, boogie factor), Jocasta (hi-hat hairspray, background vox), and Pascal (Pascal Gabriel, noise engineer). The album consisted of slightly longer versions of S-Express's "Theme" and its follow-up hits "Superfly Guy" (UK #5) and "Hey Music Lover" (UK #6), along with an album's worth of new compositions. Singer Billie Ray Martin also appeared on several tracks on its debut.
