The winning word from this year's Scripps National Spelling Bee was stromuhr, which is "a rheometer designed to measure the amount and speed of blood flow through an atery." Stromuhr combines the German words for "stream" and "clock" and was invented by Carl Ludwig in 1867. Ludwig (1816-1895) was a German medical researcher who related chemical and physical laws to biological phenomena.
Anamika Veeramani was the winner of the 2010 National Spelling Bee, which was completed this past June.
