61 Carroll, Thomas
SUBJECT AREA: Agricultural and food technology[br]b. 1888 Melbourne, Victoria, Australiad. 22 February 1968 Australia[br]Australian engineer responsible for many innovations in combine-harvester design, and in particular associated with the Massey Harris No. 20 used in the "Harvest Brigade" during the Second World War.[br]Carroll worked first with the Buckeye Harvester Co., then with J.J.Mitchell \& Co. In 1911 he was hired by the Argentinian distributor for Massey Harris to help in the introduction of their new horse-drawn reaper-thresher. Carroll recommended modifications to suit Argentinian conditions, and these resulted in the production of a new model. In 1917 he joined the Toronto staff of Massey Harris as a product design leader, the No. 5 reaper-thresher being the first designed under him. Many significant new developments can be attributed to Carroll: welded sections, roller chains, oil-bath gears, antifriction ball bearings and the detachable cutting table allowing easy transfer of combines between fields were all innovations of which he was the source.In the 1930s he became Chief Engineer with responsibility for the design of a self-propelled harvester. The 20 SP was tested in Argentina only eight months after design work had begun, and it was to this machine that the name "combine harvester" was applied for the first time. Improvements to this original design produced a lighter 12 ft (3.65 m) cut machine which came off the production line in 1941. Three years later 500 of these machines were transported to the southern United States, and then gradually harvested their way northwards as the corn ripened. It has been estimated that the famous "Harvest Brigade" harvested over 1 million acres, putting 25 million bushels into store, with a saving in excess of 300,000 labour hours and half a million gallons of fuel.Carroll retired from Massey Ferguson in 1961.[br]Principal Honours and DistinctionsAmerican Society of Agricultural Engineers C.H.

62 Lobnitz, Frederick
SUBJECT AREA: Ports and shipping[br]b. 7 September 1863 Renfrew, Scotlandd. 7 December 1932 Crookston, Renfrewshire, Scotland[br]Scottish shipbuilder, expert in dredge technology.[br]Lobnitz was the son of Henry Christian Lobnitz. His father was born in Denmark in 1831, and had worked for some years in both England and Scotland before becoming a naturalized British subject. Ultimately Henry joined the Clyde shipyard of James Henderson \& Son and worked there until his death, by which time he was sole proprietor and the yard was called Lobnitz \& Co. By this time the shipyard was the acknowledged world leader in rock-cutting machinery.Frederick was given the opportunity to travel in Europe during the late 1870s and early 1880s. He studied at Bonn, Heidelberg and at the Zurich Polytechnic, and also served an apprenticeship at the Fairfield Shipyard of John Elder \& Co. of Glasgow. One of his first tasks was to supervise the construction and commissioning of a subaqueous rock excavator, and then he was asked to direct rock excavations at the Suez Canal.In 1888 Frederick Lobnitz was made a partner of the company by his father and was to remain with them until his death, at which time he was Chairman. By this time the shipyard was a private limited company and had continued to enhance its name in the specialized field of dredging. At that time the two greatest dredge builders in the world (and deadly rivals) were situated next to each other on the banks of the Clyde at Renfrew; in 1957 they merged as Simons-Lobnitz Ltd. In 1915 Lobnitz was appointed Deputy Director for Munitions in Scotland and one year later he became Director, a post he held until 1919. Having investigated the running of munitions factories in France, he released scarce labour for the war effort by staffing the plants under his control with female and unskilled labour.[br]Principal Honours and DistinctionsKnighted 1920.
