N. D. Zelinsky
N.D. Zelinsky was born on February 6, 1861 in Tiraspol. He graduated from the University in Odessa in 11884. In 1885 he was sent abroad to have practice in research work. After returning he gave lectures in general chemistry at the same University.
In 1893 he came to Moscow. D. Mendeleyev found out about his arrival and the scientists met. Mendeleyev helped him, and Zelinsky was appointed a professor at Moscow University in the chair of analytical and organic chemistry. That year marked the beginning of Zelinskys various activities at Moscow University, where he worked to the very last days of his life.
One of the works carried out at that period brought his national recognition. Zelinsky was the first to prepare the activated charcoal and invent the Zelinsky universal charcoal gasmask.
In 1934 took an active part in the organization of the institute of Organic Chemistry.
Several principal parts in organic chemistry were found and developed by Zelinsky. He built a large school of his own and educated a real army of chemists. For his outstanding activities Zelinsky was awarded the highest orders. He died on July 31, 1953, at the age of 92.

In 1870 Pavlov entered Petersburg University to study natural sciences. Soon he decided to become a physiologist himself.
During his work at the Academy Pavlov discovered several new facts about the blood pressure. In 1890 Pavlov began to lecture on physiology in the Military Academy. Many of Pavlovs ideas were new to the students and he was a very popular lecturer.
Pavlov studied the work of the digestive system. He made many experiment on dogs. Pavlov never operated unless it was really necessary and he always used anaesthetics. He was very skilful surgeon and the dogs generally recovered very quickly.
After the Great October Revolution Pavlov was given a splendid new laboratory near Leningrad. Large sums of money were spent on this laboratory. Pavlov made great contribution to medical science.
