This article is a review of the pioneering work by B. Maćkowiak, A. Myszkier and B. Safader, written under the supervision of G. Trzaskowska, on the ELWRO Wrocław Electronics plant, responsible for producing the first computers in communist Poland. The authors of the article reviewed are former ELWRO employees, and their personal experience and memories are what makes up the publication. As a result, it avoids becoming a chronologically-arranged list of historical facts and instead offers a firsthand testimony regarding the leading Polish electronics manufacturer, emphasising the fact that its work was pioneering in nature and extremely innovative at the time. The reviewed article contains information on extremely important facts related to the economic history of Wrocław after 1945.
