William Dean (1840-1905) of the Great Western Railway presided over the conversion from broad to standard gauge under Daniel Gooch. Also transverse sleeper compartments and all-corridor trains. He was the Chief Locomotive Engineer for the GWR from 1877, when he succeeded Joseph Armstrong. He retired from the post in 1902 and was replaced by George Jackson Churchward. He designed famous steam locomotive classes such as the Duke Class and Bulldog Class.

1840 August 8th. Born the second son of Henry Dean, manager of the Hawes Soap Factory in New Cross, London.

Following an early education at the Haberdashers' Company School, he was apprenticed at the age of fifteen to Joseph Armstrong at the Great Western Railway's Wolverhampton Stafford Road Works. During his eight year apprenticeship he attended Wolverhampton Working Men's College in the evening, excelling in mathematics and engineering. Upon completion of his apprentice years in 1863 he was made Joseph Armstrong's chief assistant.

A year later, Joseph Armstrong was promoted to the position of the GWR's Chief Locomotive Engineer and moved to Swindon Works. George Armstrong, Joseph's brother, succeeded him as Northern Division locomotive superintendent, with Dean under him as Stafford Road works manager. This arrangement lasted until 1868, when Joseph Armstrong made Dean his chief assistant in Swindon.

Upon Joseph Armstrong's sudden death of a heart attack in 1877, Dean became Chief Locomotive Engineer.

At this time, the broad gauge was still in use, although conversion to standard gauge was well underway. Several of Dean's early designs were "convertible" locomotives, which could be easily rebuilt into standard gauge.

1889 His wife Ellen Nicholls Happinell died at Clevedon. She was the eldest daughter of Edward Cousins. [1]

Dean was ill during his final years as Chief Locomotive Engineer, and he increasingly allowed Churchward to take on the day-to-day responsibilities. He retired in June 1902 to a house that had been bought for him in Folkestone.

1905 September 4th. Died at Folkestone

Under him the works at Swindon had during that time grown greatly, the number of men employed being about 13,000; and during his long experience he saw the introduction of many improvements in connection with the railways of this country. To his skill and ingenuity are due a number of changes, which resulted in greater comfort and convenience to passengersIn 1893 he contributed a Paper to this Institution on "Tensile Tests and Chemical Analyses of Copper Plates from Fire-boxes of Locomotives on the Great Western Railway," which was read and discussed in conjunction with the Second Report to the Alloys Research Committee.

He took a keen interest in the Volunteers, and joined their ranks in the early "sixties"; while at Swindon he worked very hard in connection with his regiment, and held the rank of major. He was also a Justice of the Peace for Wiltshire.

His death took place after a long illness at his residence in Folkestone, on 24th September 1905, in his sixty-sixth year.

He became a Member of this Institution in 1868, and was a Member of Council from 1892 until his death. He was also a member of the Institution of Civil Engineers.
