A lexander Petrovich Karpinski was born in 1847 in Turinskie Rudniki. His family lived in an old house, which was built in 1791. When he was only 6 months old his family moved to Yekaterinburg, there he spent his childhood. After his father’s death he was sent to Petersburg College of Mines and he graduated it with honours.

Being a good professional he was suggested a lot of working places, but he chose the Urals without hesitation. He got a post of a gold mining supervisor. Having become a Ph.D, he got a job at Petersburg Institute of Mines.

All his life he didn’t lose a connection with his place of birth. Working in the regions of Lyalya, Lobva, Tura he dealt with the coal, ore and copper deposits. Alexander Petrovich Karpinski had been carrying out his work for 70 years and was considered to be a ‘Lomonosov’ of geology. He became the best expert in mineralogy and worked out a method of historical-geological analysis (now it is a basis of modern geology). Moreover Alexander Petrovich Karpinski was an honorary member of Belgian, Italian and Philadelphian Academies of Science.

Y. S. Fedorov was a versatile scientist. He was a gifted crystallographer, mineralogist, geologist, geometrician, engineer and t eacher. His scientific heritage is more than 500 scientific works. Only after his work was published, the crystal lost its ‘magic’ character, because Y. S. Fedorov explained its main properties. He worked out 230 geometrical laws of crystallography. His mineral collection is one of his great merits.

He came to Turinskie Rudniki in 1894. Manganese and dolomites were needed for ferrous metallurgy development, and geological exploration was needed for deposits revelation. That is why Y. S. Fedorov was invited to the region.

The work was great and very hard because of severe taiga conditions. He had been carrying out investigations for 5 years. The research methods were absolutely unique. Usually geologists made an observation and then charted hypothetical deposits. Fedorov invented a new way. He made a net of prospecting shafts in an area of 4000 square km. The entire rock specimens (more than 80,000) were charted. That map had a 1:84000 scale on 297 pages. That map was unique and helped to discover new deposits.

Y. S. Fedorov opened a museum. The collection had two parts. The first one demonstrated the geographical map of the region in general. The second showed the specimen from mines. By 1918 there were 220,000 of exhibits, 51,000 of sections (шлиф) 2,500 of different drawings and a unique library.

Y. S. Fedorov visited these places as he said: ‘…to date with my beloved garnet nature’.
