what was his connection with nazism?
In 1933, the Rockefeller Foundation created a fund to help support refugee academics, and Bohr discussed this programme with the President of the Rockefeller Foundation, Max Mason, in May 1933 during a visit to the United States. He offered the refugees temporary jobs at the institute, provided them with financial support during the rise of Nazism
Niels Bohr
The rise of Nazism in Germany prompted many scholars to flee their countries, either because they were Jewish or because they were political opponents of the Nazi regime. In 1933, the Rockefeller Foundation created a fund to help support refugee academics, and Bohr discussed this programme with the President of the Rockefeller Foundation, Max Mason, in May 1933 during a visit to the United States. 
what is the exact mass of an electron Approximately 1/1836 that of the proton is the electron a positive charge or a negative charge or is it neutral? Negative charge can you describe any experiment in short where this charge can be produced? UNANSWERABLE what are the names of the scientists who are involved in the discovery of this negative charge? J. J. Thomson what are the applications of this kind of charge? Cathode ray tubes,  computer monitors, television sets,  Vacuum tubes, etc. what are some of the experiments conducted by that scientist you mentioned? One such experiment was Cathode rays. He marked the paths of particles of matter charged with negative electricity which educational institution did he attend? Owens College in Manchester, then moved to  Trinity College what subjects did he study? He  obtained his Bachelor of Arts degree in mathematics what were some of the awards conferred to him? Fellow of the Royal Society  and appointed to the Cavendish Professorship of Experimental Physics what were the names of some of the scientists he collaborated with during his research and experimental work? Charles Glover Barkla, Niels Bohr, Max Born, William Henry Bragg any discoveries made by the second scientist? He contributes  to understand atomic structure and quantum theory. He developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another.

Niels Bohr [SEP] Nazism and Second World War
The rise of Nazism in Germany prompted many scholars to flee their countries, either because they were Jewish or because they were political opponents of the Nazi regime. In 1933, the Rockefeller Foundation created a fund to help support refugee academics, and Bohr discussed this programme with the President of the Rockefeller Foundation, Max Mason, in May 1933 during a visit to the United States. Bohr offered the refugees temporary jobs at the institute, provided them with financial support, arranged for them to be awarded fellowships from the Rockefeller Foundation, and ultimately found them places at institutions around the world.
