From
Wilhelm
Röntgen[1]
Munich, 18 September
1906
Very
esteemed
Colleague:
Permit
me
to
turn to
you
with two
requests!
In
order
to
complete
my
collection
of
papers
on
electrodynamics,
I would also like to have
reprints
of
your
papers.[2]
So,
my
first
request is
that
you
be
so
kind
as
to
send
me
these
reprints.
For
quite
a
long
time
I
have
been
very
interested
in
Brownian
motion,
and
thus
also
in
your
publications
on
that
topic.[3]
Could
you
be
so
especially
kind
as
to tell
me
about
your
reaction
to
the doubts that
Gouy
has
expressed
regarding
the
assumption
that
molecular
collisions
are
the
cause
of motions of
small
corpuscles.[4]
This
assumption is
certainly
very
difficult
to
reconcile
with the second law
of
thermodynamics.
I
shall be
extremely
grateful
if
you
could
grant
me
these
requests.
Respectfully yours,
W. C.
Röntgen

To
Jost Winteler
Bern, 3
November
1906
Highly
esteemed Professor
Winteler:[1]
Deeply
shaken
by
the terrible
tragedy
that
burst
so suddenly
upon
you
and
your
children,[2]
I feel
compelled
to
express my
deepest condolences,
even
though
I know
very
well how
impotent
my
feeble
words
are
in
the
face
of
such
pain.
All
those
who have
personally experienced
the
goodness
of
your
heart
and have
seen
how
earnestly
you
have
always
strived for
truth
and
justice,
must
shudder
at
the
thought
of
the terrible
blow
that
blind
fate
has
dealt
you.
The dear
departed
has shown
me so
much
kindness,
while
I
caused her
only sorrow
and
pain;[3]
that distresses
me
all
the
more
at this hour!
But of
what
use
is
all this? All
