[Quadruple anniversary of Bohumil Eiselt].

Internist Bohumil Eiselt belongs to eminent personalities of the Prague Medical Faculty. Since the summer semester in 1861, he purposefully and systematically persuaded the Czech as the teaching language at the Prague Medical Faculty. In 1871, his clinic was recognized as the first Czech clinic of the not yet divided Prague Medical School. In 1881, he managed to get the largest clinic of internal medicine in the general teaching hospital which, after the activation in 1883, was transferred at the Czech Medical School. It ensured the Czech medics good conditions for learning internal medicine. Bohumil Eiselt stood at the cradle of the Czech Medical Association and the Journal of Czech Physicians, founded in 1862, whose introduction was necessary for the development of professional medical Czech. The same importance had his publishing the edited compendium Professional pathology and therapy in the years 1878-1889 and organizing the first congresses of Czech medical doctors.
