Circumscope

Circumscope
Inventor	William Murdoch

The Circumscope is invented by Detective William Murdoch using a pair of Thomas Brackenreid's opera glasses. The name comes from circum (Latin for around) and scope (Greek for target or to watch).

The Circumscope is a version of what we, today, would recognize as a periscope. The first periscope-type device was designed by Johannes Gutenberg in the 1430s but the device we are familiar with wasn't perfected until World War I.
