 He completed the class of Alexander Brullov at the Imperial Academy of Arts in 1841-1848.His graduation honours entitled Grimm to take an Academy-sponsored study tour of Italy and France, but it was cancelled due to the revolutions of 1848 in Europe.Rather than waiting until the end of hostilities, Grimm opted for a study tour of the Caucasus (1849–1850) that exposed him to the wealth of vernacular Georgian and Armenian architecture.
