Rev. N. B. Baldwin... was born in New Milford, Litchfield Co. Conn., and August 23, 1824. His father, Rev. Daniel Baldwin, was an esteemed and highly useful Baptist minister. Norman was educated at Hamilton Literary and Theological Institute, now Madison University, from which he graduated in 1846. It is proper to state in this connection that he was a classmate with Rev. George C. Baldwin, D.D., who graduated in 1844, and in the same year accepted the call of the First Baptist Church in Troy, N. Y., where he has, from that time to the present, been a successful and highly-honored pastor.

In October, 1846, Norman B. Baldwin became pastor of the Baptist Church at Monticello, Sullivan Co., N. Y. After a most prosperous service he accepted the unanimous call of the Bethesda Baptist Church, New York City, June 1, 1849, in which God greatly blessed him, but disease compelled him to leave New York, and he accepted the call of the Second Southwark (now Calvary) Baptist Church, Philadelphia, and entered on his labors February 1, 1854. From this body he went out with a colony of two hundred and twenty members, and organized the Olivet Baptist Church, October 7, 1856. They built the fine edifice at the southeast corner of Sixth and Federal Streets. Extensive revivals, in which hundreds were converted and immersed, together with the other labors of his office, so impaired his health that in September, 1864, he closed his eleven years' pastorate in Philadelphia, and retired to his farm near Colmar, Montgomery Co. As his health soon began to improve he gave short periods of service to New Britain Baptist Church, Bucks County, Bristol Church, and the Gwynedd Baptist Church. In November, 1869, he entered upon his labors as pastor of the Montgomery Baptist Church, near Colmar Station, and since that time God has also blessed his ministry among that people. He has baptized over five hundred persons during his ministry. He is now (1885) the oldest pastor, both in age and time of service, in this part of the State, in the Baptist or any other denomination.
