Quote by Fritz Zwicky

"The true scientist is prepared to bear privations and, if need be, the scorn of the rest of the scientific fraternity."

"I have from an early age abjured the use of meat, and the day may come when such an attitude will index the civilisations and methods of men."

"The 'crackpot' designation by the integrated orthodox scientific hierarchies has often concealed the sad facts of priority struggles and the overt suppression of unwelcome discoveries."

"One of the most important responsibilities of a leader is to ask hard questions and demand hard answers."
