Tawell
was
tried
for
the
murder
of
the
woman,
and
astounding
revelations
were
made
as
to
his
character.
Transported
in
1820
for
the
crime
of
forgery,
he
obtained
a
ticket-of-leave,
and
started
as
a
chemist
in
Sydney,
where
he
flourished,
and
after
fifteen
years
left
it
a
rich
man.
Returning
to
England,
he
married
a
Quaker
lady
as
his
second
wife.
He
confessed
to
the
murder
of
Sarah
Hart,
by
prussic
acid,
his
motive
being
a
dread
of
their
relations
becoming
known.
Tawell
was
executed,
and
the
notoriety
of
the
case
brought
the
telegraph
into
repute.
Its
advantages
as
a
rapid
means
of
conveying
intelligence
and
detecting
criminals
had
been
signally
demonstrated,
and
it
was
soon
adopted
on
a
more
extensive
scale.
In
1845
Wheatstone
introduced
two
improved
forms
of
the
apparatus,
namely,
the
'single'
and
the
'double'
needle
instruments,
in
which
the
signals
were
made
by
the
successive
deflections
of
the
needles.
Of
these,
the
single-needle
instrument,
requiring
only
one
wire,
is
still
in
use.
In
1841
a
difference
arose
between
Cooke
and
Wheatstone
as
to
the
share
of
each
in
the
honour
of
inventing
the
telegraph.
The
question
was
submitted
to
the
arbitration
of
the
famous
engineer,
Marc
Isambard
Brunel,
on
behalf
of
Cooke,
and
Professor
Daniell,
of
King's
College,
the
inventor
of
the
Daniell
battery,
on
the
part
of
Wheatstone.
They
awarded
to
Cooke
the
credit
of
having
introduced
the
telegraph
as
a
useful
undertaking
which
promised
to
be
of
national
importance,
and
to
Wheatstone
that
of
having
by
his
researches
prepared
the
public
to
receive
it.
They
concluded
with
the
words:
'It
is
to
the
united
labours
of
two
gentlemen
so
well
qualified
for
mutual
assistance
that
we
must
attribute
the
rapid
progress
which
this
important
invention
has
made
during
five
years
since
they
have
been
associated.'
The
decision,
however
vague,
pronounces
the
needle
telegraph
a
joint
production.
If
it
was
mainly
invented
by
Wheatstone,
it
was
chiefly
introduced
by
Cooke.
Their
respective
shares
in
the
undertaking
might
be
compared
to
that
of
an
author
and
his
publisher,
but
for
the
fact
that
Cooke
himself
had
a
share
in
the
actual
work
of
invention.
