Wolf was born in Fällanden, near Zurich. He studied at the universities of Zurich, Vienna, and Berlin. Encke was one of his teachers. Wolf became professor of astronomy at the University of Bern in 1844 and director of the Bern Observatory in 1847. In 1855 he accepted a chair of astronomy at both the University of Zurich and the Federal Institute of Technology in Zurich. An observatory was opened at Zürich in 1864, largely due to Wolf's efforts, and he was appointed as director. Wolf was greatly impressed by the discovery of the sunspot cycle by Heinrich Schwabe and he not only carried out his own observations, but he collected all the available data on sunspot activity back as far as 1610 and calculated a period for the cycle of 11.1 years. In 1848 he devised a way of quantifying sunspot activity. The Wolf number, as it is now called, remains in use. In 1852 Wolf was one of four people who discovered the link between the cycle and geomagnetic activity on Earth. Wolf also wrote on prime number theory and geometry, then later on probability and statistics - a series of papers discussed Buffon's needle experiment in which he estimated π by Monte Carlo methods. Wolf also made significant contributions to the history of science. He discovered where the correspondence of Johann Bernoulli and several other of the younger Bernoullis was stored and, as a result, this correspondence was later published. Upon the establishment of the Zurich Polytechnikum he was named head librarian; during his tenure he assembled a valuable collection of early printed books on astronomy, mathematics, and other branches of science. Wolf was a broad and prolific author. His Mathematics, Physics, Geodesy, and Astronomy saw six editions between 1852 and 1893. His History of Recent Astronomy, published in 1877, and his Handbuch der Astronomie, published 1893, were both extremely popular in the late nineteenth and early twentieth century. He contributed four volumes to the Biographies of Swiss Men of Science and two to the Handbuch der Mathematik. Wolf reported the results of his historical researches on sunspots in his Astronomische Mittheilungen, a kind of private research journal which appeared in 13 volumes between 1852 and 1893, and of which Wolf was the sole author. His sunspot number monitoring work continued at the Zürich Observatory until 1979, when it was transferred to Brussels. The Wolf sunspot number, as it is now called, remains the favored historical indicator of past solar activity.VISIT MY EBAY STORE FOR OTHER ITEMS OF INTEREST(Click This Link) Shipping: Free media rate shipping in US.
