In which U.S. city did Robert B. Leighton spend his professional career?
Robert B. Leighton Robert Benjamin Leighton ( ; September 10, 1919 – March 9, 1997) was a prominent American experimental physicist who spent his professional career at the California Institute of Technology (Caltech). His work over the years spanned solid state physics, cosmic ray physics, the beginnings of modern particle physics, solar physics, the planets, infrared astronomy, and millimeter- and submillimeter-wave astronomy. In the latter four fields, his pioneering work opened up entirely new areas of research that subsequently developed into vigorous scientific communities.
Marshall Taylor Marshall Walter "Major" Taylor (November 26, 1878 – June 21, 1932) was an American track cyclist who began his amateur career while he was still a teenager in Indianapolis, Indiana. He became a professional racer in 1896, at the age of 18, and won the sprint event at the 1899 world track championships in Montreal, Quebec, Canada, to become the first African American to achieve the level of world champion and the second black athlete to win a world championship in any sport. Taylor also set numerous world records in the sprint discipline in race distances ranging from the quarter-mile (0.25 mi ) to the two-mile (2 mi ). Taylor was an American sprint champion in 1899 and 1900, and competed races in the U.S., Europe and Australasia. He retired in 1910, at the age of 32, to his home in Worcester, Massachusetts.
