Scientist of the Day - Leoš Janáček
Leoš Janáček, a Czech composer, died Aug. 12, 1928, at the age of 74. He shines as one of the Summer Triangle of great Czech composers, along with Antonín Dvořák and Bedřich Smetana. So far as we know, Leoš Janáček had no interest in science and made no contribution to natural philosophy. But we are going to celebrate his birthday today anyway, for reasons that may become apparent, or may not. A charming portrait photo shows Leoš and his wife Zdenka, when Leoš was age 27 (first image).
On Feb. 8 and Mar. 8 of 1865, Gregor Mendel of the Augustinian Abbey of St. Thomas in Brno, Moravia (now the Czech Republic), gave two papers to the Natural History Society of Brno, in which he announced the results of ten years of experiments on crosses with pea-plants. The findings, which revealed that traits lost in one generation can return in the next in a mathematically predictable way, were unexpected, and also unappreciated. Mendel is the second from the right in the photograph from 1862, holding a pea plant (second image).
