“ After studying at the Realachule and the polytechnic school at Caasel, Mond worked in 1855 under Hermann Kolbe at Marburg and went in 1856 to Heidelberg to work under Robert Wilhebn Bunsen. In 1859 he began his industrial career in a miniature soda-works at Ringkuhl near Cassel, where he began the researches that led to his sulphur recovery process ; he next became manager of a factory at Mainz for the production of acetic acid by wood distillation. Thence proceeding to Cologne, he worked there at the production of ammonia from waste leather. ”

“ Ayrton accepted the chair of physics and telegraphy, and proceeding to Japan created a laboratory for teaching applied electricity. The first of its kind, this laboratory served as a model for those which Ayrton himself organised in England later, and through them for numerous other laboratories elsewhere. During the five years in Japan Ayrton with his colleague, Professor John Perry, carried out an extraordinarily large amount of experimental work ”

“ Ayrton acted as professor of applied physics at Finsbury from 1881 till 1884, and then became first professor of physics and electrical engineering in the Central Technical College, a post which he held till his death. ”

“ The instruments have served as prototypes for the measuring instruments which have come into use in all countries, as electric power has become generally employed for domestic and commercial purposes. Ayrton and Perry also invented a clock meter and motor meter which served as models for the meters now used, and would have brought them an immense fortune, had they not abandoned their patents at too early a date. ”

“ In 1896 he gave 100,000l. under a special trust to found and equip the Davy-Faraday Laboratory, in a house next to the Royal Institution, for research in chemistry and physics; and by his will he left two sums of 50,000l. ”

“ After attending University College school from 1859 to 1864, he entered University College London in 1864-5, and in July 1865 and July 1866 took the Andrews mathematical scholarships for first and second year students respectively. ”
