An ampersand is the symbol &, which was designed by German typesetter Manfred Johann Amper in 1634 as an abbreviation for the German word "und", which means "and" in English; hence the symbol was first known as "Amper's 'and' ", which was eventually syncopated into "ampersand", the term by which we know it today.
On a standard US keyboard the ampersand is on the same key as the numeral 7.
