Brady Township was formed from Washington Township on 31 January 1855. It was named for the Brady family, several of whom lived within its limits. Until 1861, Brady Township also included what is now Gregg Township, Union County.
One of the most prominent early residents of Brady Township was Judge William Piatt. Piatt was born and raised in the area that is now Brady Township. His father, John Piatt, moved to the southern part of Lycoming County from New Jersey and established a tannery. William was born on 29 January 1795 and followed his father into the tannery business. He soon took an interest in the local political scene and was elected to the Pennsylvania General Assembly in 1830. He served as a legislator for three terms. Piatt became an associate judge in 1855. Piatt also served Lycoming County and Brady Township as a county auditor and as a president of both a turnpike and a bridge company.
