HEIM

heim, albert von st gallen (1849- ), swiss geologist, was born at zurich on the 12th of april 1849. he was educated at zurich and berlin universities. very early in life he became interested in the physical features of the alps, and at the age of sixteen he made a model of the todi group. this came under the notice of arnold escher von der linth, to whom heim was indebted for much encouragement and geological instruction in the field. in 1873 he became professor of geology in the polytechnic school at zurich, and in 1875 professor of geology in the university. in 1882 he was appointed director of the geological survey of switzerland, and in 1884 the hon. degree of ph.d. was conferred upon him at berne. he is especially distinguished for his researches on the structure of the alps and for the light thereby thrown on the structure of mountain masses in general. he traced the plications from minor to major stages, and illustrated the remarkable foldings and overthrust faultings in numerous sections and with the aid of pictorial drawings. his magnificent work, _mechanismus der gebirgsbildung_ (1878), is now regarded as a classic, and it served to inspire professor c. lapworth in his brilliant researches on the scottish highlands (see _geol. mag._ 1883). heim also devoted considerable attention to the glacial phenomena of the alpine regions. the wollaston medal was awarded to him in 1904 by the geological society of london.
