Arnold Beckman : ウィキペディア英語版
Arnold Orville Beckman

Arnold Orville Beckman (April 10, 1900 – May 18, 2004) was an American chemist, inventor, investor, and philanthropist. While a professor at California Institute of Technology, he founded Beckman Instruments based on his 1934 invention of the pH meter, a device for measuring acidity, later considered to have "revolutionized the study of chemistry and biology". He also developed the DU spectrophotometer, "probably the most important instrument ever developed towards the advancement of bioscience".〔 Beckman funded the first transistor company, thus giving rise to Silicon Valley. After retirement, he and his wife Mabel (1900-1989) were numbered among the top philanthropists in the United States.
==Early life==

Arnold Orville Beckman was born in Cullom, Illinois, a village of about 500 people in a farming community. He was the youngest son of George Beckman, a blacksmith, and his second wife Elizabeth Ellen Jewkes.〔 He was curious about the world from an early age. When he was nine, Beckman found an old chemistry textbook, Joel Dorman Steele's ''Fourteen Weeks in Chemistry'', and began trying out the experiments.〔 His father encouraged his scientific interests by letting him convert a toolshed into a laboratory.
Beckman's mother, Elizabeth, died of diabetes in 1912. Beckman's father sold his blacksmith shop, and became a travelling salesman for blacksmithing tools and materials. A housekeeper, Hattie Lange, was engaged to look after the Beckman children. Arnold Beckman earned money as a "practice pianist" with a local band, and as an "official cream tester" running a centrifuge for a local store.〔
In 1914, the Beckman family moved to Normal, a suburb of Bloomington, Illinois, so that the young Beckmans could attend University High School in Normal, a "laboratory school" associated with Illinois State University.〔 In 1915 they moved to Bloomington itself,〔 but continued to attend University High, where Arnold Beckman obtained permission to take university level classes from professor of chemistry Howard W. Adams.〔 While still in high school, Arnold started his own business, "Bloomington Research Laboratories", doing analytic chemistry for the local gas company.〔 He also performed at night as a movie-house pianist, and played with local dance bands.〔 He graduated valedictorian of his class, with an average of 89.41 over four years, the highest attained.〔
Beckman was allowed to leave school a few months early to contribute to the First World War effort in early 1918 by working as a chemist. At Keystone Steel and Iron he took samples of molten iron and tested them to see if the chemical composition of carbon, sulfur, manganese and phosphorus was suitable for pouring steel.〔
When Beckman turned 18 in August 1918, he enlisted in the United States Marines. After three months at marine boot camp on Parris Island, South Carolina,〔 he was sent to the Brooklyn Navy Yard, for transit to the war in Europe. Because of a train delay, another unit embarked in place of Beckman's unit. Then, counted into groups in the barracks, Beckman missed being sent to Russia by one space in line.〔 Instead, Arnold spent Thanksgiving at the local YMCA, where he met 17-year-old Mabel Stone Meinzer, who was helping to serve the meal. Mabel would become his wife.〔 A few days later, the armistice was signed, ending the war.
