Membership granted Dalton access to laboratory facilities. The Dalton family belonged to the Quaker faith, which emphasized values such as simplicity, hard work, and education. John Dalton passed away on July 27, 1844, in Manchester.

How did Dalton’s childhood influence his career?

Dalton was born into a Quaker family, where he faced financial hardships that limited his access to formal education.

His interest in meteorology began at an early age, and he meticulously recorded weather data throughout his life, accumulating over 200,000 observations. He never married and had few close relationships outside of his family.

His work on atomic theory marked one of the most significant milestones in the history of science.

Later Work and Achievements

Following the publication of his atomic theory, John Dalton continued to make significant contributions to science, particularly in the fields of chemistry and meteorology. He was the son of a modest Quaker family; his father, Joseph Dalton, was a handloom weaver, and his mother, Deborah Greenup, came from a family of tradespeople.

Dalton's dedication to his work was further underscored by his aversion to public recognition typical of Quaker modesty. In it he elaborated on some of the practical details of his theory: that the atoms within a given element are all exactly the same size and weight, while the atoms of different elements look—and are—different from one other.

Dalton's dedication to his research did not go unnoticed; he accepted an honorary Doctorate of Science from Oxford University in 1832, despite his color blindness preventing him from appreciating the color of his graduation gown. A Quaker by upbringing, Dalton faced various personal challenges, including color blindness, which he identified in himself and his brother.

This work marked the beginning of Dalton’s lifelong contribution to scientific research.

Dalton’s interest in meteorology remained strong, and in 1793, he published his first major work, “Meteorological Observations and Essays.” The book contained pioneering ideas on the behavior of gases, the nature of rain, and the origin of winds, although it received little attention at the time.

He referred to the Greek philosopher Democritus of Abdera's more abstract theory of matter, which had centuries ago fallen out of fashion, and borrowed the term "atomos" or "atoms" to label the particles. Dalton’s Law was a key development in the study of gases, as it provided a clear and quantifiable explanation of how gases interact in a mixture.

For one of his first research projects, Dalton pursued his avid interest in meteorology. His early work in meteorology culminated in the publication of "Meteorological Observations and Essays" in 1793. Born into a Quaker family in Eaglesfield, England, on September 6, 1766, Dalton enjoyed an upbringing that instilled certain values yet provided limited personal luxuries.

For example, Dalton’s assignment of atomic weights to certain elements, such as oxygen and hydrogen, was incorrect, leading to errors in his calculations. He was appointed as a tutor at the New College, a dissenting academy that provided education to students who were excluded from the established universities because of their religious beliefs.

However, as more experimental evidence accumulated in its favor, Dalton’s theory gained widespread acceptance and laid the foundation for modern chemistry. He identified red-green color blindness, which is often referred to as "Daltonism".
