Answer 2

Justus von Liebig (May 12, 1803 – April 18, 1873) was a German chemist who made major contributions to agricultural and biological chemistry, and worked on the organization of organic chemistry. As a professor, he devised the modern laboratory-oriented teaching method, and for such innovations, he is regarded as one of the greatest chemistry teachers of all time. He is known as the "father of the fertilizer industry" for his discovery of nitrogen as an essential plant nutrient, and his formulation of the Law of the Minimum which described the effect of individual nutrients on crops. He also developed a manufacturing process for beef extract, and founded a company, Liebig Extract of Meat Company, that later trademarked the Oxo brand beef bouillon cube.

Winogradsky - There were several.  Which one?

Stephen Hales, FRS (17 September 1677 – 4 January 1761) was an English physiologist, chemist and inventor. Hales studied the role of air and water in the maintenance of both plant and animal life. He gave accurate accounts of the movements of water in plants, and demonstrated that plants absorbed air. Hales discovered the dangers of breathing stale air, and invented a ventilator which improved survival rates when employed on ships, in hospitals and in prisons. Hales is also credited with important developments in the collection of gases.

Kostytchev - Couldn't find anything even with alternative spellings.

Henry Walter Bates FRS, FLS, FGS (February 8, 1825 – February 16, 1892) was an English naturalist and explorer who gave the first scientific account of mimicry in animals. He was most famous for his expedition to the Amazon with Alfred Russel Wallace in 1848. Wallace returned in 1852, but lost his collection in a shipwreck. When Bates arrived home in 1859 after a full eleven years he had sent back over 14,000 specimens (mostly insects) of which 8,000 were new to science.
