Timiryazev had founded a botanical laboratory in Moscow in 1865, which was later named the Timiryazev Agricultural Academy in his honour. He studied photosynthesis in plants, and identified chlorophyll as a crucial part of the process. In 1878, he published The Life of the Plant. He also worked to popularise Darwin's theory of evolution in Russia. In 1909, he was awarded honorary doctorates from the University of Cambridge and the University of Geneva. Photographed in 1911.
