Christian Konrad Sprengel

Died 7 Apr 1816 at age 65 (born 22 Sep 1750). German botanist and teacher whose studies of sex in plants led him to a general theory of fertilization which, basically, is accepted today. Although director of a school at Spandau and tutor in Berlin, he devoted himself chiefly to the study of flowering plants. Sprengel's 1793 treatise [illustration at left] on floral structure examines the ways that flower colors, scents, shapes, and markings work harmoniously to attract insects for pollination. A clergyman and botanist, he spent his life researching the role played by the wind and insects in the fertilization of flowers. Although Sprengel's work was neglected by his contemporaries, Charles Darwin later praised Sprengel's work and brought it brought to public attention.
