Example text

This house is undoubtedly 32 Palace Embankment, where A. I. Friedmann, a doctor's assistant in the Court's Medical Unit, was living. Friedmann's involvement in the work of the leading body in the Social-Democratic Organization of secondary school students (which had its editorial board publishing a handwritten Voice of Secondary Educational Establishments and was intending to issue the Newsletter of the Students' Organization) allowed us to suggest that the resolutions of the meetings of senior school students of the 2nd Gymnasium were drawn up with most active participation of its two students Friedmann and Tamarkin.

And it was at the meeting of students of the 2nd Gymnasium that it was proposed to hold an all-city council of all the elected monitors of gymnasia and technical schools. By December 1905 the "Northern SocialDemocratic Organization of Secondary Schools" was formed, which was headed by a committee consisting of 15 people representing at first about 100 (in April, 200) students. This committee, which was soon named the Central Committee, consisted mainly of representatives of St. Petersburg secondary schools, which were divided into four districts: the Vyborg district, the Vasilievsky Island district, the City district (which included the 2nd Gymnasium, as well as other educational establishments located in the center of the city) and the Teachers' district, which was named for the District Teachers' Training School, whose students were extremely active.

We further learn that the organization's Central Committee was directly linked with the St. Petersburg committee of the RSDWP (the Russian Social Democratic Workers' Party) and that it had three hectographs which printed hundreds of copies of leaflets. This is what gives "flesh and blood" to the reminiscences of V. I. Smirnov, given to one of the authors of this book, saying that on the way to the sessions of the mathematical circle Friedmann often called into an apartment house where people working at the Imperial Court lived, to "drop" stacks of leaflets in one of the apartments.
