Famous Engineers & Scientists (FI+LN) Crossword Puzzle
November 8, 2020

This Famous Scientists crossword puzzle took a long time to make because of all the names that I managed to squeeze into the matrix. The way this one works is the person's first initial and completely spelled-out last name, indicated by (FI+LN) in the clue, is used as the answer. For instance, filter transfer function developer Stephen Butterworth would be written as SBUTTERWORTH. There are at least sixteen names here There are at least sixteen names here with which you should be familiar. Good luck!
