Imagine a world without batteries. It would be a much different world, in which the automobile and the telephone would have developed differently and probably later, a world without many of the conveniences of modern life and without some of the necessities. The battery, ever smaller and more powerful, defines much of our modern comforts and advances. There were many scientific and technological advances on the way to those smaller and more powerful batteries.

A pioneer in the development of electrical science, Nicholas Joseph Callan was born on 22 December 1799 in Darver, Ireland. He started the priesthood at Navan Seminary, and continued his studies at St. Patrick’s College Maynooth, where he studied natural and experimental philosophy under Dr. Cornelius Denvir. After his ordination as priest in 1823, Callan pursued his doctorate in divinity in Rome, where he became acquainted with Galvani and Volta’s work in the study of electricity, and recognized the potential to put it to practical and commercial use with powerful batteries.
