A c1850 antique
pedometer by Negretti & Zambra, arguably London's
finest 19th century instrument makers. Housed in a
Moroccan leather fitted case with the owner's initials
V.Y.C.G. The green silk lining is marked in gold with
the company's royal crest and below this "Negretti and
Zambra London, 45 Cornhill, 122 Regent St & Crystal
Paklace". The pedometer is in perfect working. The
gilt metal casing holds the mechanism which is fronted
with a white enamel dial bordered with Roman numerals
and a hinged glass front. On the lower edge there are
adjusting mechanisms to reset the dial and adjust the
speed of the gearing to "S" or "F". The pedometer as
we know it was invented by Thomas Jefferson in 1786
but Leonardo da Vinci and the Romans before him made
devices to measure walking distance. |
