Thus he distrusted, and probably never fully accepted, Gay-Lussac's conclusions as to the combining volumes of gases. He lived for more than a quarter of a century with his friend, the Rev. W. Johns (1771–1845), in George Street, Manchester, where his daily round of laboratory work and tuition was broken only by annual excursions to the Lake District and occasional visits to London.

In 1840 a paper on the phosphates and arsenates, often regarded as a weaker work, was refused by the Royal Society, and he was so incensed that he published it himself. Cambridge, MA: Harvard University Press. The statue erected in his honor in London further signifies that Dalton was more an icon of intellect and research, and his earnings were fundamentally overshadowed by his extensive contributions to science and education rather than personal wealth accumulation.

1856. Dalton’s pioneering efforts not only opened up new scientific inquiries but also offered a greater understanding and awareness of the challenges faced by those with color vision deficiencies.

John Dalton Discovery and Innovations

1. Atomic Theory: Dalton’s most famous contribution, the atomic theory, proposed that all matter is made up of small, indivisible particles called atoms.

   He stated that chemical reactions involve the rearrangement of these atoms, which remain unchanged in chemical processes, thus conserving their mass. He discovered that in a mixture of gases, the total pressure is the sum of the partial pressures of each individual gas. He served as president of the Manchester Literary and Philosophical Society from 1817 until his death.

   Thousands attended his procession, reflecting the profound impact of his work on atomic theory and chemistry. The first attack he suffered in 1837, and a second in 1838 left him with a speech impediment, though he remained able to conduct experiments. He attended several of the earlier meetings of the British Association for the Advancement of Science at York, Oxford, Dublin, and Bristol.

   Raised in a modest Quaker family, his parents, Joseph Dalton and Deborah Greenup, were both from humble backgrounds and adhered to the Quaker tenets of simplicity and education.

   In the fourth essay, he remarks:

   I see no sufficient reason why we may not conclude that all elastic fluids under the same pressure expand equally by heat and that for any given expansion of mercury, the corresponding expansion of air is proportionally something less, the higher the temperature.

   Growing up in a modest home where his father worked as a handloom weaver, Dalton faced the challenges of poverty early on, which curtailed his access to formal education. Dalton used his own symbols to visually represent the atomic structure of compounds. It seems, therefore, that general laws respecting the absolute quantity and the nature of heat are more likely to be derived from elastic fluids than from other substances.

   He thus enunciated Gay-Lussac's law, stated some months later by Joseph Louis Gay-Lussac.

2. Henry, William Charles.
   

   In 1832, he was awarded a doctorate degree at Oxford University. His work laid the foundational principles for modern chemistry and physics, establishing the concept of atoms as the basic units of chemical elements. His engagement with the society allowed him to interact with other scientists and intellectuals, further broadening his scientific horizons.

   Focus on Meteorology and Initial Research Dalton’s initial research focused heavily on meteorology; he maintained meticulous records of meteorological observations, which he began in his youth and continued throughout his life.

   He held peculiar and unfounded views about chlorine. His personal account of his own color blindness led to the condition being occasionally termed as “Daltonism.”

3. Meteorological Observations and Studies: Dalton kept meticulous records of meteorological conditions, contributing significantly to the field of meteorology.
