H. Meier qualified as Dr.Med.Vet. in Berne, Switzerland, with a thesis on Digifolin, ein neues Digitalis-praeparat und seine Wirkung beim Pferd. He was recruited by Dr Arnold Theiler* and came to South Africa in 1919 to work at the Armoedsvlakte research station near Vryheid. The next year he was one of several co-authors with Theiler of a paper on "The causes and prevention of Lamziekte" in the Journal of the Department of Agriculture, Union of South Africa (1920, Vol. 1, pp. 221-224). He returned to Switzerland in 1921. However, several years later he was again one of the co-authors of an extensive report by Theiler on "Lamsiekte (parabotulism) in cattle in South Africa", published in the 11th and 12th Reports of the Director of Veterinary Education and Research (1927, Part 2, pp. 821-1361).
