Henry Brown
What He Invented: The Modern-Day Fireproof Safe
Why It Is Important: When Henry Brown patented a “receptacle for storing and preserving papers on November 2, 1886” this was a fire and accident safe container made of forged metal that could be sealed with a lock and key. Anyone who has ever had important documents stored in a safe and saved in a fire can thank Brown.
