A cryptic drawing, a treasured notebook, a stolen key, a mechanical man, and a hidden message from Hugo's dead father form the backbone of this intricate, tender, and spellbinding mystery...
Clockmakers were artisans and master craftsmen who designed
and built clocks by hand. They designed
the clocks, the components that made them work, and often the tools to create
or repair their pieces. They have to
have fine motor coordination and the ability to work with tiny, delicate
machinery. Today most clocks are
factory-made, but there are still clockmakers who work in jewelry stores and
antique shops repairing old clocks and watches.
Timekeeping devices
date back to ancient civilizations, who used the stars and astronomical bodies
moving across the sky to track time.
Sundials and water clocks were used by the Egyptians, Babylonians,
Greeks, and Chinese. During the Dark and
early Middle Ages, Islamic water clocks, Indian incense clocks, and European
hourglasses were invented. Later in the
Middle Ages, some of these techniques were combined to create a mechanical
clock. This invention was based on the
bell-striking alarm used in monasteries.
After the
invention of the mainspring, it was possible to being create smaller clocks,
such as those designed by two of the most famous scientists – Leonardo DaVinci
and Galileo Galilei. They each used the
concept of the pendulum, working with different lengths to produce a desired
timekeeper. In 1656, Dutch designer
Christian Huygens built upon their designs to create a clock more accurate than
any before.
It was a naval
disaster in 1707 that changed the future of timekeeping devices. The Scilly Naval Disaster was one of the
worst maritime disasters in British history.
Around 1700 sailors lost their lives to a wreck in severe weather. The disaster was attributed to several
factors, including the navigators inability to correctly calculate their
position. Following this disaster,
governments offered a prize to anyone who could discover a way to determine
longitude. The electric clock, invented
in 1840, became the new standard.
During the Boer
War (1899-1902), the wristwatch became the symbol of masculinity. Then in the 1940s, quartz timers became the
basis for precise measurement of time. During
the 20th century, battery-driven watches, quartz wristwatches, transistors,
and precise plastic parts were all invented, bringing accurate timekeeping to
the masses. Today, the most accurate
clocks are atomic clocks, which can be accurate to within a few billionths of a
second per year. These are the clocks
used to calibrate all other clocks and timekeeping devices.
