Fingerprint identification and lie detectors are well-known tools of law enforcement today, but both were quite revolutionary when they were introduced. In this week's episode of the Futility Closet podcast we'll describe the memorable cases where these innovations were first used.

We'll also see some phantom ships and puzzle over a beer company's second thoughts.

Intro:

In 1892, Bostonians realized that the architects of their new library had hidden their name in the façade.

In 1918, a California businessman built a 7,900-ton steamer out of ferrocement.
