Harlan J. Brothers
'''Harlan J. Brothers''' (19?? &ndash; present) is a teacher, musician, and inventor living in Branford, CT.  

In 1997, while examining the [[sequence]] of counting numbers raised to their own power ( {a<sub>n</sub>}=n<sup>n</sup> ), Brothers discovered some simple algebraic formulas that yielded the number 2.71828..., the universal constant <i>e</i>, also known as the base of the [[natural logarithm]].  Like its more famous cousin [[&am(contracted; show full)

In addition to working as a teacher, Brothers holds five patents and is a trained and actively performing musician.
