Wilhelm Weinberg - Biography

Biography

Weinberg was born in Stuttgart and studied medicine at Tübingen, Berlin and Munich, receiving an M.D. in 1886. He returned to Stuttgart in 1889, where he remained running a large practice as a gynecologist and obstetrician until he retired to Tübingen a few years before his death in 1937. Much of his academic life he spent studying genetics especially focusing on applying the laws of inheritance to populations.

Additional contributions by Weinberg to statistical genetics included the first estimate of the rate of twinning – Realizing that identical twins would have to be same-sex, while dizygotic twins could be either same or opposite sex, Weinberg derived the formula for estimating the frequency of monozygotic and dizygotic twins from the ratio of same sex and opposite twins to the total of maternities. Weinberg also estimated that the heritability of twinning itself was close to zero.

Famous quotes containing the word biography:

    “In how few words, for instance, the Greeks would have told the story of Abelard and Heloise, making but a sentence of our classical dictionary.... We moderns, on the other hand, collect only the raw materials of biography and history, “memoirs to serve for a history,” which is but materials to serve for a mythology.”
    —Henry David Thoreau (1817–1862)

    “A biography is like a handshake down the years, that can become an arm-wrestle.”
    —Richard Holmes (b. 1945)

    “The death of Irving, which at any other time would have attracted universal attention, having occurred while these things were transpiring, went almost unobserved. I shall have to read of it in the biography of authors.”
    —Henry David Thoreau (1817–1862)
