15 Hetzel, Max
[br]b. 5 March 1921 Basle, Switzerland[br]Swiss electrical engineer who invented the tuning-fork watch.[br]Hetzel trained as an electrical engineer at the Federal Polytechnic in Zurich and worked for several years in the field of telecommunications before joining the Bulova Watch Company in 1950. At that time several companies were developing watches with electromagnetically maintained balances, but they represented very little advance on the mechanical watch and the mechanical switching mechanism was unreliable. In 1952 Hetzel started work on a much more radical design which was influenced by a transistorized tuning-fork oscillator that he had developed when he was working on telecommunications. Tuning forks, whose vibrations were maintained electromagnetically, had been used by scientists during the nineteenth century to measure small intervals of time, but Niaudet- Breguet appears to have been the first to use a tuning fork to control a clock. In 1866 he described a mechanically operated tuning-fork clock manufactured by the firm of Breguet, but it was not successful, possibly because the fork did not compensate for changes in temperature. The tuning fork only became a precision instrument during the 1920s, when elinvar forks were maintained in vibration by thermionic valve circuits. Their primary purpose was to act as frequency standards, but they might have been developed into precision clocks had not the quartz clock made its appearance very shortly afterwards. Hetzel's design was effectively a miniaturized version of these precision devices, with a transistor replacing the thermionic valve. The fork vibrated at a frequency of 360 cycles per second, and the hands were driven mechanically from the end of one of the tines. A prototype was working by 1954, and the watch went into production in 1960. It was sold under the tradename Accutron, with a guaranteed accuracy of one minute per month: this was a considerable improvement on the performance of the mechanical watch. However, the events of the 1920s were to repeat themselves, and by the end of the decade the Accutron was eclipsed by the introduction of quartz-crystal watches.[br]Principal Honours and DistinctionsNeuchâtel Observatory Centenary Prize 1958.

19 Guillaume, Charles-Edouard
[br]b. 15 February 1861 Fleurier, Switzerlandd. 13 June 1938 Sèvres, France[br]Swiss physicist who developed two alloys, "invar" and "elinvar", used for the temperature compensation of clocks and watches.[br]Guillaume came from a family of clock-and watchmakers. He was educated at the Gymnasium in Neuchâtel and at Zurich Polytechnic, from which he received his doctorate in 1883 for a thesis on electrolytic capacitors. In the same year he joined the International Bureau of Weights and Measures at Sèvres in France, where he was to spend the rest of his working life. He retired as Director in 1936. At the bureau he was involved in distributing the national standards of the metre to countries subscribing to the General Conference on Weights and Measures that had been held in 1889. This made him aware of the crucial effect of thermal expansion on the lengths of the standards and he was prompted to look for alternative materials that would be less costly than the platinum alloys which had been used. While studying nickel steels he made the surprising discovery that the thermal expansion of certain alloy compositions was less than that of the constituent metals. This led to the development of a steel containing about 36 per cent nickel that had a very low thermal coefficient of expansion. This alloy was subsequently named "invar", an abbreviation of invariable. It was well known that changes in temperature affected the timekeeping of clocks by altering the length of the pendulum, and various attempts had been made to overcome this defect, most notably the mercury-compensated pendulum of Graham and the gridiron pendulum of Harrison. However, an invar pendulum offered a simpler and more effective method of temperature compensation and was used almost exclusively for pendulum clocks of the highest precision.Changes in temperature can also affect the timekeeping of watches and chronometers, but this is due mainly to changes in the elasticity or stiffness of the balance spring rather than to changes in the size of the balance itself. To compensate for this effect Guillaume developed another more complex nickel alloy, "elinvar" (elasticity invariable), whose elasticity remained almost constant with changes in temperature. This had two practical consequences: the construction of watches could be simplified (by using monometallic balances) and more accurate chronometers could be made.[br]Principal Honours and DistinctionsNobel Prize for Physics 1920.

20 Johansson, Carl Edvard
[br]b. 15 March 1864 Orebro, Swedend. 30 September 1943 Eskilstuna, Sweden[br]Swedish metrologist and inventor of measuring-gauge blocks.[br]Carl Edvard Johansson was first apprenticed to a shoemaker, but he soon abandoned that career. In 1882 he went to America to join his brother Arvid working at a sawmill in the summer; in winter the brothers obtained further general education at the Gustavus Adolphus College at St Peter, Minnesota. They returned to Sweden in November 1884 and in the following year Carl obtained employment with a small engineering firm which rented a workshop in the government small-arms factory at Eskilstuna. In his spare time he attended the Eskilstuna Technical College and in 1888 he was accepted as an apprentice armourer inspector. After completion of his apprenticeship he was appointed an armourer inspector, and it was in his work of inspection that he realized that the large number of gauges then required could be reduced if several accurate gauges could be used in combination. This was in 1896, and the first set of gauges was made for use in the rifle factory. With these, any dimension between 1 mm and 201 mm could be made up to the nearest 0.01 mm, the gauges having flat polished surfaces that would adhere together by "wringing". Johansson obtained patents for the system from 1901, but it was not until c.1907 that the sets of gauges were marketed generally. Gauges were made in inch units for Britain and America—slightly different as the standards were not then identical. Johansson formed his own company to manufacture the gauges in 1910, but he did not give up his post in the rifle factory until 1914. By the 1920s Johansson gauges were established as the engineering dimensional standards for the whole world; the company also made other precision measuring instruments such as micrometers and extensometers. A new company, C.E.Johansson Inc., was set up in America for manufacture and sales, and the gauges were extensively used in the American automobile industry. Henry Ford took a special interest and Johansson spent several years in a post with the Ford Motor Company in Detroit, Michigan, until he returned to Sweden in 1936.[br]Principal Honours and DistinctionsHonorary Doctorates, Gustavus Adolphus College, St Peter and Wayne University, Detroit.
