NOTES
This piece comes from a large collection of letters to, from, and concerning Frederick Gardner Cottrell, a prominent American inventor and physical chemist. Best known for his invention of the electrostatic precipitator, a device which revolutionized emission-heavy industries, Cottrell rose to prominence for his endeavors to fund American scientific research through the establishment of the Research Corporation for Science Advancement. Cottrell was highly regarded by the other leading scientific minds of his age, a fact reflected in this collection of his letters with historic figures in research, academia, and American politics. Among these are Cottrell’s correspondences with Alexander Graham Bell, Thomas Edison, and Nobel laureates William Ramsay (discoverer of the noble gases) and J. J. Thompson (discoverer of the electron), as well as exchanges with two American presidents, Herbert Hoover and Woodrow Wilson.
