The work of many Warsaw architects, active in the nineteenth and early twentieth centuries, is still little known. Thus, there is insufficient knowledge about the Warsaw buildings from that period, which to a large extent have not survived due to the destruction of World War II and the doctrinal assumptions of the post-war reconstruction. Its reconstruction, along with scientific reflection, is not only due to the need - even if only virtually - to save the lost architectural heritage, but also due to the conservation works carried out on the existing objects. The article presents the professional profile of Edward Goldberg, an architect working in the indicated period mainly in Warsaw. His work has not been the subject of comprehensive studies so far. The analyses carried out in the article allowed for the presentation of many typical solutions characteristic of Warsaw architecture at the turn of the 19th and 20th centuries, especially residential - from luxurious tenement houses to workers' housing and public buildings. The text focuses not only on stylistic solutions, but also on functional and sometimes technical aspects.
