Carl Wilhelm Scheele

My greatest delight is to be occupied with chemical experiments.

I have no other ambition than to be a useful member of society.

The air consists of two kinds of elastic fluids, one of which is absorbed by burning bodies, and the other not.

I have found that a certain acid, which I call 'fluoric acid,' is contained in fluor spar.

I have discovered a new acid, which I call 'molybdic acid,' from the mineral molybdena.

I have found that the black mineral called 'manganese' contains a new metal.

It is a great satisfaction to me to be able to contribute something to the advancement of chemistry.

My health is not always the best, but my love for chemistry keeps me going.

I have no time for idleness; there is always something new to investigate.

The more I experiment, the more I realize how much there is still to learn.

I often work late into the night, for the experiments demand my full attention.

I have isolated a substance from milk, which I call 'lactic acid.'

I have discovered a new acid in fruits, which I call 'citric acid.'

The study of nature is an endless source of wonder and delight.

I prefer to work in my laboratory than to attend social gatherings.

I have found that a certain acid, which I call 'tartaric acid,' is present in wine.

My experiments are my greatest companions.

I have discovered a new acid in gallnuts, which I call 'gallic acid.'

The pursuit of truth is the noblest endeavor.

I have found that a certain acid, which I call 'uric acid,' is present in urine.
