Manhattan (with Columbia and NYU) probably deserves the title of "Borough of Universities," but the Bronx probably deserves to hold on to "Borough of Parks."
The Bronx is known as "THE BOROUGH OF UNIVERSITIES AND PARKS?"

"Another factor that makes for the good health of the community is the great park area of the borough, aggregating 4,300 acres of park lands, greater than that of the four other boroughs combined. Pelham Bay Park is the largest park in the City of New York."

The Bronx also is regarded as the "Borough of Universities," with more schools of higher education in our community than any place of its size in the world.
29 October 1935, New York Times, "College Week Planned," pg. 19:
A week of collegiate activity during which the institutions of higher learning in the Bronx will hold exercises to illustrate that community's claim to the title "The Borough of Universities" was planned yesterday by a group of educational, civic and professional leaders in the office of James J. Lyons, Borough President, in the County Building at 161st Street and Grand Concourse.
20 May 1939, New York Times, pg. 18:
"As soon as the other property owners see what the thirteen lucky ones have been getting, as soon as they realize that the Bronx tax rate is the lowest of any of the five boroughs, that the Bronx is the 'Borough of Universities and Parks' and that it is a place of beauty and culture, they will come of their own free will."
