Robert Andrews Millikan

"The California Institute of Technology (CalTech) rose to prominence when Robert A. Millikan was called to Pasadena in 1921 as new university president. Millikan was known for his far-reaching ambitions both as a physicist and as a science manager. He put CalTech on the map as a top university by inviting the worlds most renowned scientists for guest lectures and by hiring internationally distinguished scientists to new chairs. With theoretical physicist Paul Epstein, a pupil of Sommerfelds, Millikan brought modern atomic physics to CalTech in the early 1920s, and with Kármán, he pursued the same strategy a few years later in order to lure the best available aerodynamicist from Europe to Pasadena."

"Science walks forward on two feet, namely theory and experiment."

"Since the origin of the "penetrating rays" was still uncertain, Dr. Russell Otis and myself in the summer of 1923 went to the top of Pikes Peak for the sake of making absorption experiments upon these radiation at the highest altitude to which we could carry large quantities of absorbing materials. For if the rays were not of cosmic origin they did not need to be more penetrating than are the gamma rays from radioactive materials, while if they were of cosmic origin the sounding balloon experiments of Bowen and myself had shown that they must be very much harder (more penetrating) than anybody had thus far assumed. What was needed was absorption experiments to determine just what sort of rays they actually were."

"In 1832 the English astronomer Airy, in making a report to the British Association on the state of astronomical science throughout the world, remarked that he was unable to say anything about America astronomy because, so far as he knew, no public observatory existed in the United States. It was in the 1840s that the Cincinnati Observatory, the Naval Observatory in Washington, and the Harvard College Observatory in Cambridge, Massachusetts, were founded—the three pioneer institutions in a development that has continued with increasing acceleration ever since."
