Sir William George Toop Goodman KBE MICE MIEE MIEAust (14 March 1872 – 4 February 1961), until his knighthood invariably referred to as "W. G. T. Goodman", was an engineer and administrator who supervised the installation of New Zealand's first electric tramway and went on to oversee the foundation and growth of the Municipal Tramways Trust in Adelaide, South Australia.
William was born in Kent, either in St. Peters or Ramsgate, a son of William Henry Goodman and his wife Emma Ann Goodman, née Limeburner, and educated at St. George's School in Ramsgate. He later studied at King's College London and perhaps Finsbury Technical College. He was articled to Squire & Newton of London, then joined Maudslay & Field. In 1891 he joined the firm variously reported as Poole & Wight or Poole & White and worked on the Blackpool electric tramways, the Liverpool electric railway, the City and South London electric railway, and the City and South London Railway. He has also been reported as working for Simpson and Co. of London, and for his father, who may have been a consulting engineer or a carpenter. After leaving his employment in 1894 he may have visited America and Germany to gain further technical knowledge and experience. In October 1894 he was in Hobart, Tasmania as a representative of the Brush Electrical Engineering Company setting up that company's exhibit at the International Exhibition, then installing an electric lighting plant for the Mount Lyell Mine reducing works, and advising on the feasibility of installing a hydro-electric generator on the Zeehan Falls for a company floated by Samuel McLean.
