Highly
esteemed
Mr.

Federal
Council:
I
thank
you

be able to work
so soon again as a
teacher
in Switzerland. I have
already petitioned
for
my
release
from
the Austrian
civil

Esteemed Professor
and Mrs.
Stern,
Two
days ago
I
was
appointed
to the
Polytechnic
in
Zurich[1] (hallelujah!)
and I have
already
submitted
my
imperial
royal
resignation here.[2]
We old folks
and the
two
baby
bears[3]
are
immensely happy
about
it, so
that
I
simply
had
to send
you
the
news.
We will
pull
out
of here
this
summer
already.[4]
Best
regards
to
you
and
your
children.[5]
Until
we see you again,
your
A.
Einstein
&
wife
