||1799: Joachim Barrande ... geologist and paleontologist. He settled in Prague (1832), at first as an engineer. While surveying the proposed route for a horse-drawn railway, he became interested in the local fossil-bearing rocks there. From 1840, he turned to the study of these fossils in the strata of the central Bohemian basin. In his lifetime, he gathered some 3500 species of graptolites, brachiopoda, mollusca, trilobites and fishes, showing a wide variety of life forms in the Early Paleozoic era. (The Paleozoic era spanned 540-245 million years ago.) He meticulously recorded his findings in Système silurien du centre de la Bohême, which remains a fine reference work. The first volume was published in 1852, and was followed by 20 more in his lifetime. He opposed Darwin's theory of evolution, instead advocating the theory of catastrophes. Pic.

||1829: Mathematician and academic Norman Macleod Ferrers born. In 1871 he first suggested to extend the equations of motion with nonholonomic constraints.[4] His another treatise on "Spherical Harmonics," published in 1877, presented many original features. In 1881 he studied Kelvin's investigation of the law of distribution of electricity in equilibrium on an uninfluenced spherical bowl and made the addition of finding the potential at any point of space in zonal harmonics.
