Do
you
know
of
any
other
invention
that
was
named
after
its
inventor?
The
Earl
of
Sandwich
was
an
Englishman.
He
lived
in
the
18th
century.
The
Earl
of
Sandwich
was
rich,
but
he
liked
to
play
cards
for
money.
He
often
played
for
24
hours,
and
didn’t
even
stop
to
have
his
meals.
He
ordered
his
servants
to
bring
him
some
meat
and
bread.
He
put
the
meat
between
the
two
pieces
of
bread
and
held
the
food
in
his
left
hand
and
played
cards
with
his
right
hand.
People
liked
his
idea,
and
from
then
on
they
ate
bread
and
meat
as
he
did.
From
the
name
Sandwich,
we
get
the
