... PERSONAL HISTORY Carson was born on March 22, 1922, in Lake Charles, Louisiana, where his father Charles William Jeffries was postmaster en c! his mother Yancey Dunning a Latin teacher.

... Photographs of the luminescence of decaying excitons from the droplets taken by Carson and his students appeared on national television and the NBC evening news reported "a new state of matter." As a matter of interest we report here (according to Eugene Commins, department chair at the time) that Carson once took over the weekly colloquium and gave a superb ad lib talk on electron-hole droplets when the scheduled speaker canceled out.

... Within weeks he is getting results, usually in a new field his knowledge and proficiency in experimentation permit him to enter entirely new fields, competing effectively with scientists in wellequipped industrial or government laboratories who are not obliged to prepare and deliver regular lectures. In each new field he rapidly became a leading and innovative practitioner, winning international recognition of his contributions.

... Soon thereafter, when I arrived on the scene in the summer of 1950, Professor Birge asked me to contact Bloch to get his evaluation of Carson, who had completed his degree under Bloch. I reported that Bloch's comments were highly favorable, indicating that he judged Carson to be a genuinely superior c,~,n~lirl~,t.e where~non Birds nror,~rler1 with the official appointment.
