Heroes of the Telegraph
·
John Munro
105
Meanwhile
his
brother
Werner
had
been
turning
his
attention
to
telegraphy,
and
the
correspondence
which
never
ceased
between
the
brothers
kept
William
acquainted
with
his
doings.
In
1844,
Werner,
then
an
officer
in
the
Prussian
army,
was
appointed
to
a
berth
in
the
artillery
workshops
of
Berlin,
where
he
began
to
take
an
interest
in
the
new
art
of
telegraphy.
In
1845
Werner
patented
his
dial
and
printing
telegraph
instruments,
which
came
into
use
all
over
Germany,
and
introduced
an
automatic
alarm
on
the
same
principle.
These
inventions
led
to
his
being
made,
in
1846,
a
member
of
a
commission
in
Berlin
for
the
introduction
of
electric
telegraphs
instead
of
semaphores.
He
advocated
the
use
of
gutta-percha,
then
a
new
material,
for
the
insulation
of
underground
wires,
and
in
1847
designed
a
screw-press
for
coating
the
wires
with
the
gum
rendered
plastic
by
heat.
The
following
year
he
laid
the
first
great
underground
telegraph
line
from
Berlin
to
Frankfort-on-the-Main,
and
soon
afterwards
left
the
army
to
engage
with
Mr.
Halske
in
the
management
of
a
telegraph
factory
which
they
had
conjointly
established
in
1847.
In
1852
William
took
an
office
in
John
Street,
Adelphi,
with
a
view
to
practise
as
a
civil
engineer.
Eleven
years
later,
Mr.
Halske
and
William
Siemens
founded
in
London
the
house
of
Siemens,
Halske
&
Co.,
which
began
with
a
small
factory
at
Millbank,
and
developed
in
course
of
time
into
the
well-known
firm
of
Messrs.
Siemens
Brothers,
and
was
recently
transformed
into
a
limited
liability
company.
