At the beginning of the Tverskoy Boulevard in Moscow there is a statue of Timiryazev which was unveiled on 4 November 1923, sculpted by Sergey Merkurov and laid out by the architect Osipov. Timiryazev is depicted in the gown of Cambridge University where he was awarded an honorary doctorate. The granite pedestal bears the inscription of 'the curve of plant physiology' which Timiryazev elucidated. In October 1941 the statue was overturned by a Fascist bomb, but after a few hours it was back in its place. Its lower half still bears the marks caused by bomb splinters.
