Yegor Zolotarev's Life Story
Yegor Zolotarev was born in Saint Petersburg, which was then part of the Russian Empire. His father, Ivan Vasilevich Zolotarev, was a merchant. His mother was Agafya Izotovna Zolotareva.
Early School Days
In 1857, when Yegor was ten years old, he started studying at the fifth St Petersburg gymnasium. This school was special because it focused a lot on mathematics and natural science. He was a very good student and finished school in 1863, earning a silver medal.
That same year, even though he was quite young, he was allowed to attend classes at St Petersburg University. He couldn't officially become a student until 1864 because of his age.
University and Teachers
At the university, Yegor learned from some famous mathematicians. These included Osip Somov, Pafnuty Chebyshev, and Aleksandr Korkin. He became very good friends with Aleksandr Korkin, and they worked together on scientific ideas.
In November 1867, Yegor completed his first big research paper. It was called "About the Integration of Gyroscope Equations" and was like a master's degree project. Just ten months later, he finished another important paper. This one was called "About one question on Minima." Because of this work, he was allowed to start teaching at St Petersburg University.
Teaching and Research
Yegor Zolotarev started by teaching differential calculus to science students. Later, he taught integral calculus and other math topics to new students. For most of his time as a teacher and professor, he also taught advanced students about elliptic functions.
In December 1869, he finished another major research paper. This one was titled "About the Solution of the Indefinite Equation of Third Degree x³ + Ay³ + A²z³ - 3Axyz = 1."
Travels and Big Discoveries
In 1872, Yegor took his first trip outside Russia. He visited Berlin and Heidelberg in Germany. In Berlin, he attended lectures by Karl Weierstrass, a very famous mathematician.
In 1874, Yegor became a full member of the university staff as a lecturer. In the same year, he completed his most important research, which was his doctoral thesis. It was called "Theory of integer Complex Numbers with an Application to Integral Calculus." In this work, he proved an important method created by his teacher Chebyshev. This method helped mathematicians figure out if certain complex math problems could be solved using simpler steps, like logarithms.
Professor and Academy Member
In 1876, Yegor Zolotarev was made an extraordinary professor. After his former teacher, Osip Somov, passed away, Yegor took his place as an assistant member of the Academy of Sciences. This was a very high honor for a mathematician.
A Sad Ending
Yegor Ivanovich Zolotarev's amazing career ended too soon. He was on his way to his country home, called a dacha, when he had a terrible accident. He was hit by a train at the Tsarskoe Selo station. Sadly, he passed away on July 19, 1878, from a serious infection.
It's important not to confuse Yegor Ivanovich Zolotarev with another mathematician named Vladimir Mikhaelovich Zolotarev. Vladimir worked on different math topics later on.
