Nature makes penicillin; I just found it
Scottish biologist, physician, microbiologist, and pharmacologist. His best-known discoveries are the enzyme lysozyme in 1923 and the world's first antibiotic substance benzylpenicillin (Penicillin G) from the mould Penicillium notatum in 1928.
Remember that sometimes not getting what you want is a wonderful stroke of luck
Life is either a daring adventure or nothing at all
Never discourage anyone...who continually makes progress, no matter how slow.
A capacity, and taste, for reading gives access to whatever has already been discovered by others
Work is a necessary evil to be avoided
Friendship improves happiness, and abates misery, by doubling our joys, and dividing our grief
