Who discovered absorption?

Absorption, as a scientific concept, has been explored by various scientists throughout history, but it is most notably associated with the work of Johannes Kepler in the early 17th century, who studied the absorption of light. Additionally, the phenomenon of absorption in chemistry was further developed by figures such as Robert Boyle and later, John Dalton, who contributed to understanding gas absorption. Each of these contributors helped lay the groundwork for the broader understanding of absorption in different scientific fields.
