One of the pioneering activities of the great surgeon, which aimed to raise the prestige of the Iasi medical center and create the climate for higher medical education was the course of Topographic Anatomy, Dressings and Instruments, which began on August 1, 1863, and included 14 lessons. Becoming a professor at the Faculty of Medicine, he contributed to the development of the surgery school then in its infancy, being considered "the greatest surgeon in the country". In recognition of his merits, at the first Congress of Romanian Physicians held in Bucharest in 1884, he was elected Honorary President. His achievements are also recognized at European level, his collection of stones from patients operated in the “St. Spiridon” Hospital being awarded at the International Medical Exhibition in Vienna.
There are many facts that highlight the integrity of his character, education, discipline, humanitarian spirit. Thus, at the age of 61, he voluntarily enrolled, together with his son, in the War of Independence of 1877, where he was decorated with the Star of Romania and the Crown of Romania in the highest ranks and with numerous Austrian, Polish and Russian Orders. The personality of L. Russ senior contributed to the prestige enjoyed by the Iasi medical school.
