His account of this phenomenon to the Manchester Literary and Philosophical Society in is the first recorded description of colour blindness, or as it became known, Daltonism.

Over the following years, Dalton conducted extensive research on the subject, culminating in the publication of his paper, 'Extraordinary facts relating to the vision of colours', in which he proposed that his own colour blindness was the result of his vitreous humour the jelly-like part of his eye possessing an abnormal blue tint, thus acting as a filter for certain wavelengths of light. However, post-mortem examination of his eyes in , performed upon his prior request, revealed their contents to be "perfectly colourless.

By the turn of the nineteenth century, the emergence of new experimental techniques enabled Dalton to expand on his early meteorological work; specifically, the absorption of water vapour by air at different temperatures. While his proposals for some exact formulations were incorrect he thought that the formula for water was OH, rather than H2O , his ideas were revolutionary and laid the foundations for the development of all modern chemistry. It was for his work on atomic theory that in , Dalton became one of the first two recipients of the Royal Medal, a prestigious award presented annually by the Royal Society for "the most important contributions to the advancement of natural knowledge.

Dalton continued his scientific investigation into a wide range of subjects until his death in He remained an active member of the Manchester Literary and Philosophical Society and, from , was a Fellow of the Royal Society; his election citation stated that his "talents, acquirements and exertions are well known to his fellow labourers in the cause of Science".

John Dalton FRS John Dalton was an English chemist, physicist, and meteorologist, best known for introducing the atomic theory into chemistry and for his work on human optics.

The first paper he delivered before the society was on color blindness, which afflicted him and is sometimes still called Daltonism. Dalton arrived at his view of atomism by way of meteorology, in which he was seriously interested for a long period: he kept daily weather records from until his death, his first book was Meteorological Observations , and he read a series of papers on meteorological topics before the Literary and Philosophical Society between and Arnold Thackray describes how John Dalton's book on meteorology led to his discovery of the nature of atoms.

He proceeded to calculate atomic weights from percentage compositions of compounds, using an arbitrary system to determine the likely atomic structure of each compound. If there are two elements that can combine, their combinations will occur in a set sequence.
