Holmdel Township is a township in Monmouth County, New Jersey, United States. As of the 2010 United States Census, the township's population was 16,773, reflecting an increase of 992 (+6.3%) from the 15,781 counted in the 2000 Census, which had in turn increased by 4,249 (+36.8%) from the 11,532 counted in the 1990 Census.
Holmdel is located west of the Jersey Shore. The township is notable, among other things, for its historical and present connection to Bell Labs (and, later, Lucent Technologies and Alcatel-Lucent), where the transistor was first developed. Important evidence for the Big Bang was discovered at another Bell Labs facility in Holmdel by Arno Penzias and Robert Wilson, both of whom won the Nobel Prize in Physics for their work here.
Holmdel's picturesque beauty, proximity to New York City and main highways, award-winning public schools, large homes, rich history, PNC Bank Arts Center, and the presence of many high paying jobs within commuting distance led the township to be ranked the #1 "Six-Figure Town" by Money magazine and CNN for 2009.
