The work shortly describes scientific, teaching, and organisational activity of the Chair of Chemistry and then of the Division of Physical Chemistry during after-war period. Presentation is made in five short chapters, covering periods defined by substantial and characteristic processes in our country, resulting in changes in the organisation and work of the Faculty of Chemistry at the University of Warsaw. The first two chapters concern the Chair of Physical Chemistry at the Faculty of Mathematical and Natural Science in the years 1947–1955. The Department of Chemistry was founded in the 1955. The next three chapters describe the activity of the Division of Physical Chemistry in the years 1968–1989, 1990–2005, and 2005–2016 respectively. The work also contains a register, probably incomplete, of employees with university degree, who were employed at the Chair and then at the Division of Physical Chemistry during 61-year period of the activity of the Faculty, i.e. in the years 1955-2016.
