The article is dedicated to the 50th anniversary of the key area of informatics today - software engineering. In October 2018, it was 50 years since the conference, at which the professional community of programmers and scientists put into circulation and justified the term software engineering. The article is based on the forty-five-year experience of the author in software engineering and the purposes of the article are two. In the first, to mark an important date for the main branch of the country - the software industry, and on the second, to give a complete picture of the state of affairs in software engineering, recalling those who made a system-making scientific contribution to the development of the industry. The article consists of three sections. In the first, outlines the origins and conditions that led to the emergence of software engineering. In the second, systematic results are given and the authors of these results are indicated. At the same time, such parts of software engineering are considered: programming in the aspect of the structured programming; modularization as a basis for software reuse and reuse; life cycle modeling, the importance of which is that it not only led to life cycle management, but also opened up new processes, identified new products and resources necessary for the implementation of these processes and made it possible to move on to “programming in large” that required the creation of new methods tools and professions; empirical software engineering, now, is a section of software engineering, represented by a large number and variety of metrics, tools and methods for measuring and analyzing results; a software culture that claims that only teams with a certain culture and maturity can create high-quality and reliable software; software economics and software cost estimation models; green information technologies and software, ecosystems. The third section deals with the formulation of education in software engineering, and in particular in Ukraine.
