The inauguration has been announced of a Patterson Medal to be awarded annually to a resident of Canada or Newfoundland for achievement in meteorology. The Medal has been founded by the friends and professional associates of Dr. John Patterson, the retiring controller of the Meteorological Service of Canada and honorary professor of meteorology in the University of toronto. After graduating from the University of Toronto in 1900, Dr. Patterson went to the Caven-disVLaboratory, Cambridge, with an 1851 Exhibition Science Research Scholarship. In 1902 he became professor of physics at the University of Allahabad, and soon afterwards he was appointed Imperial meteorologist to the Government of India. He joined the Meteorological Service of Canada in 1910 and became director in 1929. During the First World War, Dr. Patterson worked with the British Admiralty to develop a commercial process for the extraction of helium from natural gas. After the War, to meet the demands of aviation, he trained young graduates for the Canadian Meteorological Service, and when the Second World War broke out, he had already laid the foundation of a great meteorological service which was able to meet the demands of the British Commonwealth Air Training Plan. He is best known for his pioneering work in the exploration of the upper atmosphere by means of balloon meteorographs and for improvements to the cup anemometer and mercury barometer.
