Heroes of the Telegraph

John Munro

Mr.
Cooke
was
an
officer
in
the
Madras
army,
who,
being
home
on
furlough,
was
attending
some
lectures
on
anatomy
at
the
University
of
Heidelberg,
where,
on
March
6,
1836,
he
witnessed
a
demonstration
with
the
telegraph
of
Professor
Moncke,
and
was
so
impressed
with
its
importance,
that
he
forsook
his
medical
studies
and
devoted
all
his
efforts
to
the
work
of
introducing
the
telegraph.
He
returned
to
London
soon
after,
and
was
able
to
exhibit
a
telegraph
with
three
needles
in
January,
1837.
Feeling
his
want
of
scientific
knowledge,
he
consulted
Faraday
and
Dr.
Roget,
the
latter
of
whom
sent
him
to
Wheatstone.
At
a
second
interview,
Mr.
Cooke
told
Wheatstone
of
his
intention
to
bring
out
a
working
telegraph,
and
explained
his
method.
Wheatstone,
according
to
his
own
statement,
remarked
to
Cooke
that
the
method
would
not
act,
and
produced
his
own
experimental
telegraph.
Finally,
Cooke
proposed
that
they
should
enter
into
a
partnership,
but
Wheatstone
was
at
first
reluctant
to
comply.
He
was
a
well-known
man
of
science,
and
had
meant
to
publish
his
results
without
seeking
to
make
capital
of
them.
Cooke,
on
the
other
hand,
declared
that
his
sole
object
was
to
make
a
fortune
from
the
scheme.
In
May
they
agreed
to
join
their
forces,
Wheatstone
contributing
the
scientific,
and
Cooke
the
administrative
talent.
The
deed
of
partnership
was
dated
November
19,
1837.
A
joint
patent
was
taken
out
for
their
inventions,
including
the
five-needle
telegraph
of
Wheatstone,
and
an
alarm
worked
by
a
relay,
in
which
the
current,
by
dipping
a
needle
into
mercury,
completed
a
local
circuit,
and
released
the
detent
of
a
clockwork.
