On the history of computer algebra in Keldysh Institute of Applied Mathematics

Brief retrospective review and main references concerned Computer Algebra (CA) researches and applications in Keldysh Institute of Applied Mathematics (Russia Academia of Science) are presented. In the Institute CA was used in various areas: Applied Celestial Mechanics, Mathematics, Robotics, Hydromechanics, Applied Calculation Methods. Some original program systems were elaborated. During several years the work devoted to classification of existing systems and their possibilities were done. Conferences and seminars concerned CA applications in mechanics were organized. A language of recursive functions REFAL was created in the Institute. Later it was modified and intensively used in various fields, in particular CA. Many ideas and results which we can find in researches on CA and close fields in Keldysh Institute are still interesting today.
