ALTHOUGH he was not an engineer, the late "Captain" John Williamson, whose death took place last Friday, played a most important part in connection with the introduction of the marine steam turbine for mercantile vessels. When disaster overtook the turbine-engined destroyers Viper and Cobra, the future of the marine steam turbine was in grave jeopardy. The ship owning companies were not anxious to undertake the risks of pioneering work, and, as Sir Charles Parsons himself has recorded, the fortunes of the Parsons Marine Steam Turbine Company reached a very low ebb. At this stage Captain Williamson approached the Parsons Company and also William Denny and Brothers, with proposals for the construction of a turbine pleasure steamer to run on the Firth of Clyde. The result was that the historic vessel King Edward was launched at Dunbarton in May, 1901. She was very shortly followed by the Queen Alexandra for the same owners, and by a series of cross-Channel and other vessels, culminating in the Mauretania and Lusitania. The King Edward has recently been refitted with new turbines and still, apparently, has many years of usefulness before her. Mr. Williamson was closely associated all his life with the Clyde river steamers and was the author* of a most interesting and historically valuable work on the subject which traced the development of the vessels from the time of the Comet onwards. At one time, while he was in control of his own steamers, his brothers, James and Alexander, were responsible for the management of two of the railway companies' fleets.
