The lecture will discuss how workers from factories and plants were treated beyond the Nevsky Barrier from the 18th century to the early 20th century. Attendees will learn about diseases, factory and zemstvo medicine, the first institutions for workers, and the doctors who helped change the everyday life of the industrial area and the attitude towards public health in the city. The history of the Nevsky Barrier is not only about factories, plants, and workers' quarters, but also about the daily struggle for the health of people living near production. The lecture will provide a view of the industrial area of St. Petersburg through medical history: working conditions, the lives of workers, diseases, treatment methods, and the emergence of institutions that gradually changed the quality of life. The conversation will begin with the conditions in which the workers of the Nevsky Barrier lived and worked in the 18th to early 20th centuries. Hard labor, dense construction, everyday difficulties, and the characteristics of the factory environment affected health more than may seem today. The lecture will discuss the common illnesses among workers and the means they used to combat diseases. Special attention will be given to the medical institutions that existed for workers, the organization of factory medicine, and the role of the zemstvo system. Another topic is the scientific-medical institution established here in the early 20th century. This narrative shows that the industrial outskirts were not only a place of hard work but also a space for new social and medical practices.
