In the early 20th century, the university outgrew its buildings and the trustees began to search for a new home. Developing Clifton for the university was too costly, and {{convert|30|acres|0|abbr=on}} of the estate had to be sold to the city as public park. A solution was achieved by a team of prominent locals who acquired the estate in north Baltimore known as the [[Homewood Campus of Johns Hopkins University|Homewood Estate]]. On February 22, 1902, this land was formally transferred to the university. The flagship building, Gilman Hall, was completed in 1915. The [[Whiting School of Engineering|School of Engineering]] relocated in Fall of 1914 and the [[Zanvyl Krieger School of Arts and Sciences]] followed in 1916. These decades saw the ceding of lands by the university for the public Wyman Park and Wyman Park Dell and the [[Baltimore Museum of Art]], coalescing in the contemporary area of {{convert|140|acre}}.<ref name="HC" />

Prior to becoming the main Johns Hopkins campus, the Homewood estate had initially been the gift of Charles Carroll of [[Carrollton, Maryland]], a planter and signer of the [[United States Declaration of Independence|Declaration of Independence]], to his son Charles Carroll Jr. The original structure, the 1801 [[Homewood Museum|Homewood House]], still stands and serves as an on-campus museum.<ref name="HH">{{cite web|url = http://www.museums.jhu.edu/homewood.php|title = Homewood House|access-date = March 4, 2015|website = JHU Museums|archive-url = https://web.archive.org/web/20150224222549/http://www.museums.jhu.edu/homewood.php|archive-date = February 24, 2015}}</ref> The brick and marble [[Federal architecture|Federal]] style of Homewood House became the architectural inspiration for much of the university campus versus the [[Collegiate Gothic]] style of other historic American universities.<ref name="HH" />

In 1909, the university was among the first to start adult [[continuing education]] programs and in 1916 it founded the nation's first [[Johns Hopkins Bloomberg School of Public Health|school of public health]].<ref>{{cite web|url = http://hub.jhu.edu/gazette/2012/september/leading-the-way-in-public-health|title = Leading the way in public health|date = September 2012|access-date = March 4, 2015|website = JHU Gazette|last = Edelson|first = Matt|archive-url = https://web.archive.org/web/20150402115321/http://hub.jhu.edu/gazette/2012/september/leading-the-way-in-public-health|archive-date = April 2, 2015}}</ref>

Since the 1910s, Johns Hopkins University has famously been a "fertile cradle" to [[Arthur Lovejoy]]'s [[history of ideas]].<ref name="Paulson1970"/>

Since 1942, the [[Applied Physics Laboratory|Johns Hopkins Applied Physics Laboratory (APL)]] has served as a major governmental defense contractor. In tandem with on-campus research, Johns Hopkins has every year since 1979 had the highest federal research funding of any American university.<ref>{{cite web|url = http://hub.jhu.edu/2014/01/02/research-spending-rankings-nsf|title = Johns Hopkins leads nation in research spending for the 34th consecutive year|date = January 2, 2014|access-date = March 4, 2015|website = JHU Hub|archive-url = https://web.archive.org/web/20150402095002/http://hub.jhu.edu/2014/01/02/research-spending-rankings-nsf|archive-date = April 2, 2015}}</ref>
