History of Segal Locks

Wikipedia article detailing a small portion of the history of the Segal Lock & Hardware Company.

The original Segal lock was developed in 1912 by Samuel Segal, a New York City Police Officer who saw a need to protect residents form thieves "Jimmying" or spreading the door frame to gain entry. The lock was quickly accepted as the best way to secure a door against unauthorized entry due to physical attack.

Samuel Segal was featured in the Locksmith Ledger in May of 1955 for his innovations and contributions to the locksmith industry.
