Jacob Aaron Westervelt
Jacob Aaron Westervelt (January 20, 1800 – February 21, 1879) was a renowned and prolific shipbuilder who constructed 247 vessels of all descriptions during his career of over 50 years. From 1853 until 1855 he was Mayor of New York City.
Caspar Kauffeldt
Caspar Henrik Berntsen Kauffeldt (19 February 1773 – 19 August 1843) was a Norwegian industrialist. He was the founder of Gjøvig Glassverk.
Kauffeldt was born at Gjøvik in Oppland, Norway. 
In 1804 he bought Gjøvig farm in a then-rural area by the river Hunnselva. In 1807 he founded the glass factory Gjøvig Glassverk on the other side of the river, creating an industrial environment and laying the grounds for a larger city there. The factory became known for its blue vases, basing the color on cobalt blue from Blaafarveverket at Åmot in Modum. 
In the 1830s, his son Wexel Hansen Kauffeldt (1801-1860) took over most of the factory administration. The operation became increasingly difficult with increasing competition from abroad. It was discontinued in 1843, and Caspar Kauffeldt died in the same year. Near the factory Kauffeldt had also erected the administration building "Kauffeldtgården". The building still stands, and was preserved in 1985.
