Eschsolts Ivan Ivanovich (Johann-Friedrich) 
(12.11.1793–19.05.1831)

MD, professor of anatomy at the University of Dorpat. 
Born in Dorpat in a poor notary family. Since childhood, he showed a love of nature. He loved to walk around Dorpat, collecting collections of plants and insects. 
After graduating from high school, Eschsolts in 1813 entered the University of Dorpat, having chosen, at the insistence of the parents, the Faculty of Medicine. However, the love of the medical profession he did not manifest, with the greatest pleasure Eschsolts was engaged in botany under the supervision of Professor Karl Ledebour. However, a dissertation in medicine was needed to complete the program of the institute. In 1815, having brilliantly passed the exams, Escholz defended his thesis for the degree of doctor of medicine, taking the topic of the study of various water tumors in the head, eyes, heart and lungs. 
Having received the post of doctor in Zlatoust, Eschols was dismissed from the post: he was attracted by the work of a naturalist. In 1815, he managed to take part in a round-the-world voyage on the Rurik, commanded by O.E. Kotzebue. He served as an assistant naturalist, whose role was planned professor at the University of Dorpat Ledebur. However, for health reasons, Ledebour could not go and was replaced by French professor A. Chamisso. 
The expedition lasted almost exactly three years. Sailors visited the Canary Islands, Brazil, rounding Cape Horn, landed in Chile, on many islands of Polynesia. Botanical, zoological, and ethnographic studies were conducted at the landing sites of Shamisso and Escholz, collecting extensive collections of plants and insects. Escholz proved himself to be a man perfectly adapted to expeditionary conditions. Friendliness, kindheartedness and unpretentiousness earned him the respect and favor of both the members of the expedition and the crew. He was very fond of Eszholz and Kotzebue, who often invited him to his cabin for conversations on various natural science topics. 
Almost a year after sailing in June 1816, the Rurik reached Petropavlovsk-on-Kamchatka. After repairing the plating in July, the ship headed north into the Bering Strait.And in this campaign Eschsolts conducted fruitful scientific research. On the shore of the bay, later named after him, he first discovered mountains consisting of pure fossil ice covered with a layer of soil on which grass and moss grew. 
Reaching 67° 30'N, they met the ice impassable for "Rurik" and were forced to turn south. 
Winter was devoted to the survey of the South Pacific, went to rest and repair the ship in San Francisco, then visited the Hawaiian and Sandwich Islands. 
In June 1817, they made another attempt to get to the north, but due to the grave condition of Kotzebue, who had received a serious injury earlier during a storm, abandoned his intention. On the way home, a number of new islands were discovered. The impressive scientific results of the expedition were published in the book by Chamisso. Six articles of Escholz are included in the book of Kotzebue. 
After the expedition was completed in 1818, Essholz became a prosector and extraordinary professor at the University of Dorpat. According to the results of expeditionary research, he published several articles on zoology and a small book that Kotzebue devoted. In this book, Eschsholz tried to make a classification of animals from mammals to fish. 
He worked for four years at university, lecturing and processing collections. Gradually, he moved away from the botany, completely switching to zoology. At the beginning of 1823, Essholz learned about the upcoming new round-the-world voyage Kotzebue on the sloop "Enterprise". Thanks to the friendly relations with Kotzebue and the support of I.F. Kruzenshtern, who oversaw the organization of this expedition, Escholza easily included in its composition in the place of a doctor and a naturalist. This time it was harder for him to leave Dorpat. At home there were a wife and two sons. He no longer saw the elder among them, who was three years old. The boy died two and a half years after his father left (Escholtz’s second son died of typhoid in 1838). 
The expedition lasted three years. Escholz collected the most extensive zoological collections that were transferred to the University of Derpt, discovered a large number of new species of animals. In addition to the monetary reward of 1000 rubles, he was awarded the Order of St. Vladimir, 4 degrees. His works were highly appreciated by the scientific community. Eschols was elected a member of the Society of Naturalists in Moscow, the Courland Society of Literature and Art, as well as a number of foreign scientific organizations. 
Upon his return, Eschsholz continued teaching at the University of Dorpat to the end of his short life, receiving the title of full professor. Wide scientific perspectives opened up before him, but an unexpected early death from typhoid fever interrupted his activity almost at the beginning of his journey. Contemporaries noted that "as a systematist, Essholz belongs to a place alongside the leading figures of zoological science". He also possessed remarkable human qualities - kindness, sympathy, justice, modesty, gentleness. His early death was a common grief at the University of Dorpat. 
Books and collections of Eschols was acquired by Moscow University. 
Buried in Dorpat.
