History and biography
The ICIAM Congress 2007, held in Zürich, happened to be in the year of Euler’s 300th anniversary. It was then clear to the organizers, that one of the invited talks should be dedicated to Euler and Euler’s work. Fortunately, Walter Gautschi accepted this invitation and presented a fascinating talk on Euler’s life, his personality, an overview of his work and some selected topics in more detail. This took place in the largest lecture hall (the “Turnhalle”), filled up to the last seat.
