Fairleigh Dickinson University is New Jersey's largest private institution of higher education, with over 12,000 students.

In 1958, the university acquired the former Twombly-Vanderbilt estate in Madison and Florham Park, New Jersey, to serve as its third campus.

The main house of the Twombly-Vanderbilt estate, now Hennessy Hall, was designed by architectural firm McKim, Mead, and White in the Georgian Revival style.

The mansion was completed in 1897 and was modeled after the wing of Hampton Court Palace designed by architect Sir Christopher Wren.

[8] The Friends of Florham, founded in 1990 by Emma Joy Dana, university librarian James Fraser, and a group of friends and colleagues works with the mission of advising and assisting the administration and board of trustees in the care, maintenance, and preservation of the Twombly Estate, known as "Florham".

Fairleigh Dickinson University has four campuses: two in New Jersey (Madison / Florham Park[8] and Teaneck / Hackensack[13]), one in Vancouver, British Columbia, and one in South East England, as well as an online platform.

[24] The West Indies Laboratory which opened in 1972 was damaged beyond repair during Hurricane Hugo in 1989 and was closed shortly afterwards in 1990.

[16] FDU has over 1,100 international students from approximately 17 countries around the world ranking it 15th nationally among their Carnegie peer group.

[31] Fairleigh Dickinson's Becton College offers more than 60 undergraduate majors to its full and part-time students.

[36] In 2012, Fairleigh Dickinson opened New Jersey's first school of pharmacy associated with a private higher education institution, at the Florham Campus.

[41] The Florham Campus library is part of the John and Joan Monninger Center for Learning and Research.

A portion of the library is housed in the old Orangerie of the Twombly-Vanderbilt estate which was built in the 1890s by McKim, Mead, and White.
