Considered to be the father of ‘modern atomic theory’, John Dalton was also a pioneer of weather forecast and was one of the first scientists to use homemade instruments to make weather observations. Much of his early works and observations using meteorological instruments laid the foundation for the study of weather forecasting. His fascination for the weather and atmosphere lead him to pursue research on ‘the nature of gases’, which in turn laid the ground on which he built the ‘atomic theory’. Today, he is known primarily for his work on atomic theory and although more than two centuries old, his theory still remains valid in the field of modern chemistry. Inquisitive by nature, his diligent research and meddlesome nature led him to make many discoveries in fields other than chemistry. He also made a study on colour-blindness, a condition from which he personally suffered. A non-conformist and ‘dissenter’, Dalton refused to accept much of his deserved fame and recognition and chose to live a simple and modest life. Today, his theories help modern scuba divers gauge oceanic pressure levels and have also facilitated cost-effective manufacturing of chemical compounds.
