Holmdel Township was formed by an act of the New Jersey Legislature on February 23, 1857, from portions of Raritan Township (now Hazlet).

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.

^Penzias and Wilson discover cosmic microwave radiation - 1965PBS. Accessed July 13, 2011. "Bell Labs built a giant antenna in Holmdel, New Jersey, in 1960. It was part of a very early satellite transmission system called Echo.... Since Penzias, Wilson, and Dicke's work, all that has changed. The measurement of cosmic background radiation (as the Holmdel telescope's noise is now called), combined with Edwin Hubble's much earlier finding that the galaxies are rushing away, makes a strong case for the big bang. By the mid 1970s, astronomers called it 'the standard model.' Arno Penzias and Robert Wilson received the Nobel Prize in physics in 1978."
