More than
once
I have
had the
impression
that
Mr.
Zangger
suffers
from the
fact
that
he has
much
too great
a
variety
and much too
great
a
number of
responsibilites,[6]
so
that
it becomes
impossible
for
him
to
devote the
desirable
amount
of
time and
energy
to
his scientific
interests.
I believe
that
it would have
a
liberating
effect
on
him if he
had
more
spare
time for these
things.
If
he has
spoken to
you
to this
effect,
then, I
think,
one
must
not
dissuade
him from
changing
his
job
unless
one
has
reason
to
believe
that
he would
not
really
have
more
free
time in his
new
job
than
he has
now,
or
that
he
is
not
suited
for
this
new job.
However, I
think that the latter
reason
would
hardly
apply
to
a
job
that he himself
has chosen to consider.
For
he has
too
much
real
experience
to
overestimate
his
knowledge
and
abilities.
Finally
it
would
seem
presumptuous
of
me
to
want
to
give
advice,
even
if
only
indirectly,
to
a
man
so
farsighted
and
experienced;
I
would
not
think
of
doing
that. Let
me
merely repeat
that
Mr.
Zangger
has
a
great
talent
for
physics
as
well,
and this
is,
after
all,
what
your
main
question
was.
Respectfully yours,
A.
Einstein

To
Friedrich Adler
[Basel,
9 February
1911]
Dear
Mr. Adler,
Cordial
greetings
from
both
of
us
from
Basel.[1]
If
the house
happens to
burn
down,[2]
or some
other
nice
thing
like
that
happens,
please
send
us a
wire
to the address, Prof. H. A. Lorentz, Leiden,
where
we
will be
staying
till
Sunday.[3]
After
that,
Mr.
Cäsar
Koch,[4]

From Richard
Swinne[1]
Riga,

February
1912
Highly
esteemed Professor Einstein:
While
working
on a
lecture,
"Uber
die
Zählung
der Atome"
["On
the
Counting
of
Atoms"]
to
be
delivered
at the local
association
of natural
scientists,[2]
I
came
to
conclusions which I
take
the
liberty
to submit to
you
as one
of the founders of
the
light
quanta
hypothesis.
