Samuel A. Groff developed the street letter box fastener. He was born 3 April 1847 in Manheim, Lancaster County, Pennsylvania[1]. He lived with his parents and siblings in Manheim, Lancaster County, Pennsylvania in 1850[2].

In 1860 he lived with his father, stepmother and siblings in Mount Joy Township, Lancaster County, Pennsylvania[3].

Samuel, originally from Pennsylvania, was a collector of fines with the Police Court since 1885 in Washington, DC. Around 1896, he came up with an improved method of fastening the letterboxes along city streets.

He invented such a fastener and received a patent for street letter box fasteners which could then be sold to the U.S. Postal Office.

Samuel possessed considerable talent for mechanics. Among his inventions were a projectile, a safeguard for streetcars, a device for catching crabs and a street indicator.

In 1900 he, his wife Louisa, and son John lived in the District of Columbia[4].

He died 7 January 1907 in Washington, D.C.[5] and was buried in Rock Creek Cemetery, Washington, District of Columbia, District Of Columbia[1].
