A daily newspaper founded by William Moseley Swain in 1836, the Ledger was the first daily to use a pony express and one of the first to use the electromagnetic telegraph.  It was also printed on the first rotary printing press from 1846.

A decline in popularity meant that the morning and Sunday editions were merged into The Philadelphia Inquirer after 1934, and it was eventually closed in 1942.
