12 Froude, William
SUBJECT AREA: Ports and shipping[br]b. 1810 Dartington, Devon, Englandd. 4 May 1879 Simonstown, South Africa[br]English naval architect; pioneer of experimental ship-model research.[br]Froude was educated at a preparatory school at Buckfastleigh, and then at Westminster School, London, before entering Oriel College, Oxford, to read mathematics and classics. Between 1836 and 1838 he served as a pupil civil engineer, and then he joined the staff of Isambard Kingdom Brunel on various railway engineering projects in southern England, including the South Devon Atmospheric Railway. He retired from professional work in 1846 and lived with his invalid father at Dartington Parsonage. The next twenty years, while apparently unproductive, were important to Froude as he concentrated his mind on difficult mathematical and scientific problems. Froude married in 1839 and had five children, one of whom, Robert Edmund Froude (1846–1924), was to succeed him in later years in his research work for the Admiralty. Following the death of his father, Froude moved to Paignton, and there commenced his studies on the resistance of solid bodies moving through fluids. Initially these were with hulls towed through a house roof storage tank by wires taken over a pulley and attached to falling weights, but the work became more sophisticated and was conducted on ponds and the open water of a creek near Dartmouth. Froude published work on the rolling of ships in the second volume of the Transactions of the then new Institution of Naval Architects and through this became acquainted with Sir Edward Reed. This led in 1870 to the Admiralty's offer of £2,000 towards the cost of an experimental tank for ship models at Torquay. The tank was completed in 1872 and tests were carried out on the model of HMS Greyhound following full-scale towing trials which had commenced on the actual ship the previous year. From this Froude enunciated his Law of Comparisons, which defines the rules concerning the relationship of the power required to move geometrically similar floating bodies across fluids. It enabled naval architects to predict, from a study of a much less expensive and smaller model, the resistance to motion and the power required to move a full-size ship. The work in the tank led Froude to design a model-cutting machine, dynamometers and machinery for the accurate ruling of graph paper. Froude's work, and later that of his son, was prodigious and covered many fields of ship design, including powering, propulsion, rolling, steering and stability. In only six years he had stamped his academic authority on the new science of hydrodynamics, served on many national committees and corresponded with fellow researchers throughout the world. His health suffered and he sailed for South Africa to recuperate, but he contracted dysentery and died at Simonstown. He will be remembered for all time as one of the greatest "fathers" of naval architecture.[br]Principal Honours and DistinctionsFRS.

13 Purvis, Frank Prior
SUBJECT AREA: Ports and shipping[br]b. 18 April 1850 London, Englandd. 20 February 1940 Seaford Downs, England[br]English naval architect.[br]Despite being one of the youngest entrants to the South Kensington School of Naval Architecture, Purvis obtained both a Whitworth Exhibition and a Scholarship. Upon graduating he commenced a career in shipbuilding that involved him in military, civil and research work in Scotland, England and Japan. Initially he worked in Robert Napier's shipyard on the River Clyde, and then in the London drawing offices of Sir Edward Reed, before joining the staff of the Admiralty, where he assisted William Froude in his classic ship experiments at Torquay. After a short spell with Sir William Pearce at Govan, Purvis joined William Denny and Bros and with his recently gained knowledge of hydrodynamics helped set up the world's first commercial ship model tank at Dumbarton. His penultimate appointment was that of Shipbuilding Partner in the Scottish shipyard of Blackwood and Gordon.In 1901 he became Professor of Naval Architecture at the Imperial University of Tokyo (succeeding Percy Hillhouse, who had become Naval Architect of Fairfield and later became Professor at Glasgow University) and it was in this role that Purvis was to achieve distinction through developing a teaching course of the highest order. It is accepted that his influence on the Japanese shipbuilding industry was profound. After nineteen years of service he retired to the United Kingdom.[br]BibliographyPurvis presented several papers to the Institution of Naval Architects and to the Institution of Engineers and Shipbuilders in Scotland, and in 1900 he assisted in the preparation of the Ships and Shipbuilding supplement to Encyclopaedia Britannica.FMW
