"Robert Adamson (26 April 1821 – 14 January 1848) was a Scottish chemist and pioneer photographer at Hill & Adamson. He is best known for his pioneering photographic work with David Octavius Hill and producing some 2500 calotypes, mostly portraits, within 5 years after being hired by Hill in 1843, before his life was cut short." - (en.wikipedia.org 30.01.2020)
