Aleksander Maciesza was the son of Siberian exiles. At present, he is counted among the most outstanding figures of Płock in the 20th century. He was a doctor by profession, but his knowledge and interests went beyond the learned medical view. Aleksander Maciesza was not only a well-known doctor, an outstanding ophthalmologist, a lover of science and anthropology, but also a social activist, local government activist, anthropologist, archeologist, photographer, but most of all he was a man of great passion for exploration. He was remembered, by the inhabitants of Płock, as a long-term president of the Płock Scientific Society, the mayor of Płock and the president of Płock in the beginning of the Second Polish Republic. His contributions to science and the city of Płock and its residents make him an extraordinary doctor, but above all an extraordinary man.
