Theodore von Kármán (1881-1963).
A graduate of what was later to become the Budapest University of Technology and Economics (BUTE), his contributions include theories of non-elastic buckling and unsteady wakes in flow around a cylinder. Like many engineers and scientist in Europe in the 1930?s concerns about the emerging political climate made that he migrated to the USA in that period.
Leó Szilárd (1889-1964).
Just after the First World War, he decided to give up his studies at Budapest University of Technology because of anti-Semitism in Hungary under the Horthy-regime that led to restriction of the number of Jewish students that could study at Hungarian universities. Son of a Jewish Civil engineer, his efforts to set up the Manhattan project in the USA together with other famous Jewish-Hungarian scientists and mathematicians such as John von Neumann, Edward Teller and Eugene Paul Wigner, made him responsible for some urban regeneration himself.
