5/1/1824 Alexander Williamson, chemist he is known for the Williamson synthesis of ethers by treating alcohol with sulfuric acid.
5/1/1825 Johann Balmer, mathematician, although he was a mathematician he is not remembered for any significant contributions in that field, he is know for establishing a formula for the visible spectral lines of the hydrogen atom called the Balmer lines or Balmer Series.
5/1/1839 Louis Chardonnet, chemist, worked for Pastuer, in 1894 he discovered a method to make rayon. It was so flammable that it was called “Mother-in-law” silk. Because a rayon dress and a match were ideal presents for a mother-in-law. I don’t know what “sicko” came up with this name, but it might be the worst I have posted. My Mother-in-Law was a great woman. I wonder how many of my chemistry students remember the rayon synthesis. This was always one of our favorite organic labs.
5/1/1852 Ramon Y Cajal biologist
