"Peter Cooper became one of New York’s prominent millionaires, yet he still saw himself as a master craftsman, 'A Mechanic of New York.' However, education was paramount on Cooper’s agenda. With the fortune Cooper had amassed from his glue business, ironworks, his patent inventions and his real estate holdings Cooper invested his money in The Cooper Union, commonly called at that time, Cooper Institute. It would be the crowning glory of his life. The cornerstone was laid in 1854.He erected an imposing six-story Italianate building between Third and Fourth Avenue at Astor Place. To support the floors and make the building fireproof the rolled structural iron beams were produced at the Cooper Hewitt & Company ironworks. These iron beams would make possible the building of future skyscrapers... Cooper Union was the first free institute to provide adult education in the fields of engineering, architecture and science for young men and women who qualified regardless of race, religion, sex or social status. It is acknowledged that although Cooper Union was Peter Cooper’s vision, it was Abram Hewitt’s brain that made it possible because he oversaw the construction of the building and served as Cooper Union’s president for over forty years."
