Clock Made by Voloskov, in the Tver Museum


This 1910 photograph shows a late 18th-century clock made by the Russian inventor Terentii Voloskov (1729–1806). The clock showed the time, the day of the week, and the month. When the photograph was taken, the clock was in the collections of the Tver Museum. Opened in 1866, the museum displayed natural and archeological items of interest from the region of Tver, as well as crafts and works of art. In 1897 the museum was allocated rooms in the Imperial Transit Palace. In 1918 it was nationalized and granted state protection. In 1921 it was allotted the entire space of the Transit Palace, where it remained until World War II. At some point the clock was transferred to the museum in nearby Rzhev, where Voloskov had lived. It disappeared during the months of German occupation, which saw heavy fighting in the Rzhev area. The image is by Russian photographer Sergei Mikhailovich Prokudin-Gorskii (1863–1944), who used a special color photography process to create a visual record of the Russian Empire in the early 20th century. Some of Prokudin-Gorskii’s photographs date from about 1905, but the bulk of his work is from between 1909 and 1915, when, with the support of Tsar Nicholas II and the Ministry of Transportation, he undertook extended trips through many parts of the empire. In 1910 he photographed a number of exhibits in the Tver Museum.

Physical Description

Glass negative (presented as a digital color composite)


  • Prokudin-Gorskii’s photographic work survives primarily in two forms: 1,901 black-and-white triple-frame glass plate negatives, made with color separation filters, which Prokudin-Gorskii used to make color prints and lantern slides; and 12 albums of sepia-tone prints, made from the glass negatives, which Prokudin-Gorskii compiled as a record of his travels and studies. The Library of Congress purchased the glass plate negatives and the albums from the Prokudin-Gorskii family in 1948. In 2004, the Library of Congress had digital color composites made from all the surviving glass negatives using a software algorithm to automatically align the color components. As with most historical photographs, title and subject identifications are corrected and enhanced through new research. Current information on the collection is at
