John Dalton, an Uncommon card

The card carries these facts from its Wikipedia article.

• Building on earlier ideas about the indivisibility of matter and his own precise measurements of combining ratios, Dalton proposed that each chemical element consists of identical atoms of characteristic weight, and that compounds are formed when atoms of different elements combine in fixed whole-number proportions.
• His A New System of Chemical Philosophy presented a coherent atomic model, supplied relative atomic weights and symbolic notation, and established the quantitative framework that shaped nineteenth-century chemistry and remains the basis of modern chemical thought.
• Dalton was also a pioneering meteorologist and physicist, he kept daily weather observations for over fifty years, formulated the first empirical law of partial pressures, and studied the behaviour of gases through his work on vapor pressure and gas solubility.
