Immigrants make music, enliven the arts in USA!

As I am listening to a CD of Mozart's Kleine Nachtmusik conducted by Bruno Walter, nee Schlesinger, Pianist and Conductor, I pay homage to a huge talent.
50 years ago, in February to be exact, Bruno Walter died in Beverly Hills.
Below Walter conducts Mozart's Requiem.

Born in Berlin 1879, he developed early on his talent of piano but switched to conducting and was one of the youngest Hofkapellmeisters in Vienna, at 24 - engaged by Gustav Mahler, who recognized his large talent.
Below Walter conducts Mahler!

But ...as with many others Bruno Walter was forced into emigration. He joined a slew of European Musicians and others who left for USA, and many more for other places, during the Hitler regime.  
Among those emigres were such notables as Albert Einstein, Arnold Schoenberg, Walter Gropius, Alma Schindler-Mahler-Werfel, Ludwig Mies van der Rohe, Hans Bethe, Thomas Mann, Marlene Dietrich, Kurt Weil, Billy Wilder, Hannah Arendt, and Hans Morgenthau, Hedy Lamarr, Otto Preminger, Franz Werfel and others.By the end of World War II, there were some 130,000 of these German and Austrian refugees living in America.
Which leads me to really want to dip into the stories about these others.
Actors, authors, architects, artists, magnates, musicians ...

But to keep it short:
For example, Albert Einstein wrote his seminal work about Mozart as emigrant in Massachusetts, about which he said "I cannot thank my Fuehrer enough" ...:-)!  With this remark Einstein showed a great sense of satirical humor!

And did you know that Hedy Lamarr wasn't just a pretty face?
We will celebrate the 100. anniversary of  her birth in Austria in 2013!

Several ended up in Hollywood.. writing film music - such as Erich Wolfgang Korngold.

This music, written for the silver screen in which Errol Flynn and others ride/sail forever young, remains even today THE Hollywood sound. Above from Robin Hood, below from The Seahawk

There can be no doubt that Korngold's music has been influenced by the genius of Wagner and Mahler.
Others became leading directors, actors and scriptwriters.
But mentioning them all would take too much of your time, chers readers.
Want to find out about them, go on ...  google ...  LOL!
