| Gustav Hertz, born 22 Jul 1887, was the nephew of Heinrich Hertz. Gustav was a German quantum physicist who, with James Franck, received the Nobel Prize for Physics in 1925 for the Franck-Hertz experiment, which confirmed the quantum theory that energy can be absorbed by an atom only in definite amounts and provided an important confirmation of the Bohr atomic model. Why was he forced to resign his professorship in 1934? |
| An Austrian who spent his adult life with the Augustinian monastery in Brunn, where he was a pioneer of the study of heredity, was born 22 Jul 1822. As a geneticist, botanist and plant experimenter, he was the first to lay the mathematical foundation of the science of genetics. Over the period 1856-63, he grew and analyzed over 28,000 pea plants. Can you name this man? |
