He independently discovered oxygen and identified several other chemical elements.

Quotes by Carl Wilhelm Scheele

The greatest discoveries are not made by those who follow the rules, but by those who dare to question them, and perhaps, bend them a little.

Advocating for independent thought

Some people collect art, I collect elements. Both are beautiful, but only one can truly explode.

Comparison of hobbies

My work is a testament to the fact that even in the smallest details, the grandest secrets can be found.

Reflecting on the significance of his work

They say I'm a solitary figure. I say, the elements are far more engaging conversationalists than most.

Responding to observations about his nature

The pursuit of knowledge is a journey, not a destination, and sometimes, the path is quite literally toxic.

Metaphor for scientific exploration

One must be willing to get one's hands dirty, and sometimes, a little burned, to truly understand the world.

Advice on practical experimentation

My greatest teacher has always been nature herself, though she often delivers her lessons with a rather sharp bite.

Acknowledging the challenges of research

They say I'm a bit eccentric. I say, the elements themselves are far more eccentric than I could ever hope to be.

Responding to personal labels

The universe is a grand puzzle, and I am merely trying to fit the pieces together, even the ones that smell a bit off.

Metaphor for scientific discovery

To truly see, one must look beyond the obvious, and sometimes, beyond the pleasant aroma.

Advocating for deeper observation

My legacy, I hope, will be not just what I found, but the questions I inspired others to ask, even if those questions lead to a few minor explosions.

Reflecting on his impact

It is not the quantity of the air, but a particular elastic fluid mixed with it, that is necessary for combustion and respiration.

Chemical Observations and Experiments on Air and Fire 1777

This elastic fluid, which I call 'fire air' (Feuerluft), is absorbed by burning substances and by animals during respiration.

Chemical Observations and Experiments on Air and Fire 1777

Phlogiston is not a simple substance, but a compound of fire air and a combustible principle.

Correspondence and notes

The acid of sugar (oxalic acid) is a distinct substance, not merely a modified form of tartaric acid.

On the Acid of Sugar 1776

Manganese contains a new metallic substance, which I call 'magnesium' (though later renamed manganese).

On Manganese 1774

The green color of plants is due to a peculiar acid, which I call 'acid of wood' (chlorophyll).

Notes and experiments

Glycerin is a sweet principle obtained from fats, and it is distinct from sugar.

On the Sweet Principle of Fats 1783

The acid of milk (lactic acid) is a unique substance, not simply acetic acid.

On the Acid of Milk 1780

All acids contain a common principle, which is 'fire air' (oxygen).
