One of the most eminent mathematicians of our time, Mark Grigorievich Krein is the author of more than 270 papers and monographs of unsurpassed breadth and quality. His work opened up new areas of mathematics and greatly enriched the more traditional ones. He educated dozens of brilliant students in the USSR and inspired the work of many mathematic...
met Mark Grigorievich Krein in the autumn of 1950. M.G. Krein was already then a world renowned mathematician with a list of publications containing more than 75 very important papers and books. He was considered to be one of the strongest experts in functional analysis and its applications. His main position at that time was in the Marine Engineer...
For more than twelve years I worked intensively with M.G.. During those years we wrote twenty papers and two books. A third book was in our plans, but we never finished it. For the remaining twelve years M.G. was mostly busy with other projects and our joint work was less intensive. At other times I remember him to be busy with large joint projects...
For many years M.G. Krein ran a mathematical seminar at the Scientists House in Odessa. This house used to be an old palace, but since the revolution it served as a kind of club for scientists. The rooms with high ceilings were very luxuri-ous, covered with expensive marble and wood paneling. Missing was only a good blackboard. The meetings were al...
M.G. Krein never traveled abroad. The reason for this was that he would not have been granted an exit visa had he applied. An exit visa for a trip abroad was considered by the authorities as a special privilege given only to the very “reliable”. He received many invitations, then he would apply for an exit visa, entailing the filling in of thick of...
M.G. Krein loved Odessa. He was well acquainted with the history of the town and even the history of the main streets. He liked especially the satirical books written about Odessa. Often he read out the funny bits for his guests. All his mature life (with a relatively short exception during World War Two) the Kreins lived in Odessa in an old apartm...
