SCHAEBERLE, shā'bėrlé, John Martin, American astronomer: b. Würtemherg, Germany, 10 Jan. 1853. He was brought to Ann Arbor, Mich., in his infancy, and was graduated from the University of Michigan in 1876 as a

civil engineer. He has, however, devoted himself to the study of astronomy, to which department of knowledge he has made valuable contributions. From 1876 to 1888 he taught astronomy in the University of Michigan, and was then called to the Lick Observatory at Mount Hamilton, Cal., where he made several important astronomical investigations. He had charge of the expedition to witness the eclipse at Cayenne in 1889, and of those for the same purpose to Chile in 1893, and to Japan in 1896. He is now, and has been for some years past, engaged in theoretical and experimental investigations on gravitation, light, heat and electricity. He is a frequent contributor to astronomical journals.
