Tretyakov started to collect art in 1854 at the age of 22; his first purchase was 10 canvases by Old
Dutch masters. He laid down for himself the aim of creating a Russian National Gallery. In his collection Tretyakov included the most valuable and remarkable products, first of all the contemporaries, from 1870 - mainly members of the society of circulating art exhibitions (
Tovarishchestvo peredvizhnyh hudozhestvennyh vystavok or
Peredvizhniki, Передвижники in Russian). He bought paintings at exhibitions and directly from artists' studios, sometimes he bought the whole series: in 1874 he acquired
V.V. Vereschagin's "Turkestan series" (13 pictures, 133 figures and 81 studies), in 1880 - his "Indian series" (78 studies). In his collection there were over 80 studies by
Alexander Ivanov. In 1885 Tretyakov bought 102 studies by
V.D. Polenov painted by the artist during journeys across
Turkey,
Egypt,
Syria and
Palestine. He also acquired
Viktor Vasnetsov's collection of the sketches made during his work on
St Volodymyr's Cathedral in
Kiev. Tretyakov had the fullest collection of such artists as:
V.G. Perov,
I.N. Kramskoi,
Ilya Repin,
Vasily Surikov,
I.I. Levitan, and
Valentin Serov. Aspiring to show the beginnings and development of the domestic school of art, Tretyakov began to acquire pictures by masters of the 18th and first half of the 19th centuries and landmarks of Old Russian painting. He also conceived the creation of a "Russian
pantheon" - a portrait gallery of famous Russians. He commissioned especially for it portraits of figures of domestic culture from leading masters of this genre -
N.N. Ge, Kramskoi,
N.V. Nevrev, Perov, Repin. In 1870-80 Tretyakov also began to collect illustrations (471 by 1893), and in 1890 he began to collect
icons. During his lifetime they were kept in his study and were not put on public display. He also had a small collection of
sculpture (9 sculptures by 1893). At first the gallery was located in Tretyakov's house in Lavrushenski pereulok. But as his collection expanded he decided to reconstruct his house to accommodate it. In 1870-1880 the house was reconstructed a number of times by the architect
Kaminski. Tretyakov wanted to transfer the gallery to the city as discreetly as possible, without any fuss; he didn't want to be in the centre of general attention and an object of gratitude. But this was not possible and he was very dissatisfied. From 1881 his gallery became popular (by 1885 it was visited by about 30 thousand people). In 1892 Tretyakov inherited a collection of Western European painting from his brother and placed it in two halls of the western school. The collection in Tretyakov's gallery was equal in importance with the largest museums in Russia at that time, and became one of sights of
Moscow. In August 1892 Tretyakov donated his collection and a private residence to Moscow. By then in the collection there were 1287 pictures and 518 graphics of the Russian school, 75 pictures and 8 figures of the West-European school, 15 sculptures and a collections of icons. with a statue of Tretyakov in front of it. On 15 August 1893 the official opening of a museum under the name "Pavel and Sergey Tretyakov City art gallery" (nowadays
Tretyakov Gallery) took place. By 1890 it was visited by up to 150 thousand people annually. Tretyakov continued to build up his collection, for example, in 1894 he donated a gallery of 30 pictures, 12 figures and a marble statue "The Christian martyrs" works by
Mark Antokolski. He was also involved in studying the collection, and from 1893 he produced its catalogue. ==Other work==
