Famous scientists

First identify the scientists who match the given clues. Their names are used to solve the hidden quote.  Lower case letters refer to the scientists’ first names and upper case letters refer to their last names. A single letter is the first letter from the appropriate name. Two consecutive letters are the first two letters from the appropriate name. Three consecutive letters are the first three letters from the appropriate name. Only use the beginning letter(s) of the scientist’s name. If the same letter(s) appear again in the puzzle, once more use the beginning letter(s).  If you can figure out an incomplete word in the quote, it can help you in identifying an unknown scientist.
