Harvard John A. Paulson School of Engineering and Applied Sciences

Harvard's efforts to provide formal education in advanced science and engineering began in 1847, when Massachusetts industrialist Abbott Lawrence gave Harvard $50,000 (equivalent to $1,300,000 in 2021) to form what became known as the Lawrence Scientific School. In making his gift, Lawrence asked:[6]

But where can we send those who intend to devote themselves to the practical applications of science? Our country abounds in men of action. Hard hands are ready to work upon our hard materials; and where shall sagacious heads be taught to direct those hands?

James Emmanuel Jr. was the first dean of the school, which hosted astronomers, architects, naturalists, engineers, mathematicians, and even philosophers.

By the late 19th century, the School faced increasing competition from the Massachusetts Institute of Technology (MIT) and was constrained by the uncertain views about its role and status by the long-serving Harvard President Charles William Eliot. Eliot was involved in at least five unsuccessful attempts to absorb MIT into Harvard.[7] As a result of such uncertainty, the Lawrence Scientific School became less of an independent entity, losing its influence and students to other parts of the university.

In 1891, industrialist Gordon McKay designated the Lawrence Scientific School his primary beneficiary; there are now 40 McKay professorships.

In 1906, the Lawrence School's scientific and engineering programs were incorporated into Harvard College and the Graduate School of Arts and Sciences, and it ceased to exist as an independent entity.

In 1914, a merger of MIT and Harvard's Applied Science departments was formally announced[8] and was to begin "when the Institute will occupy its splendid new buildings in Cambridge."[9] However, in 1917, the merger with MIT was canceled due to a decision by the State Judicial Court, so Harvard President Abbott Lawrence Lowell moved to establish the Harvard Engineering School independently instead.[10]

In 1934, the School began offering graduate-level and professional programs in engineering. During World War II, Harvard participated in the V-12 Navy College Training Program to provide training for commissioned officers. In 1942, the undergraduate Department of Engineering Sciences changed to the Department of Engineering Sciences and Applied Physics to reflect an increased emphasis on applied physics. Harvard President James Bryant Conant created what was known as "Conant's Arsenal," a research hub for defense-related engineering projects including radar jamming, night vision, aerial photography, sonar, explosives, napalm, and atomic bomb research.[11] One notable project from this era was the Harvard Mark I computer; one of the first programs to run on the Mark I was initiated on March 29, 1944, by John von Neumann, who worked on the Manhattan Project at the time, and needed to determine whether implosion was a viable choice to detonate the atomic bomb that would be used a year later.[12]

By 1945, Harvard income from government contracts was $33.5 million, the third highest among U.S. universities.[13]

Between 1946 and 1949, the Graduate School of Engineering merged its faculty with the Department of Engineering Sciences and Applied Physics into the Division of Engineering and Applied Sciences within the Harvard Faculty of Arts and Sciences.

In 2007, the Harvard Corporation and Overseers voted for the Division of Engineering and Applied Sciences to change its name to the School of Engineering and Applied Sciences (SEAS).[14][15]

In 2015, Francis J. Doyle III, former director of the Institute for Collaborative Biotechnologies, was appointed dean.[3] That year, the school was also renamed the Harvard John A. Paulson School of Engineering and Applied Sciences following a $400 million gift by Harvard Business School alumnus John A. Paulson.[16][17]

• 1919 – George Washington Pierce (PhD, 1900), Rumford Professor of Physics and director of Harvard's Cruft High-Tension Electrical Laboratory invented an oscillator that enabled a given radio station to stay "fixed" at a proper frequency and allowed multiple telephone calls to occur over a single line.
• 1938 – A cyclotron was constructed at the Graduate School of Engineering's Gordon McKay Engineering Laboratory to support research in biology and medicine as well as physics. It was projected to be the world's largest such facility. In 1942, it was sent to Los Alamos for work on the Manhattan Project to develop an atomic bomb.
• 1944 – Howard Aiken '37 (PhD) developed the Mark I series of computers, the first large-scale automatic digital computer in the U.S. Around the same time, a new generation of technically trained students began to share their knowledge well beyond Harvard's campus. Alumnus and donor Allen E. Puckett SB '39, SM '41 created an endowed professorship at SEAS, went on to define modern aerodynamics, served as CEO of Hughes Aircraft Company, and won the National Medal of Honor in Technology.
• 1952 – Nuclear Magnetic Resonance (NMR), the scientific foundation for MRI (used in modern medical imaging systems), was pioneered by Nicolaas Bloembergen, Edward Purcell, and Robert Pound. Purcell won the 1952 Nobel Prize in Physics for this discovery.[24]

• Stopping light – Lene Hau and her colleagues created a new form of matter, a Bose-Einstein Condensate, to slow light to 17 meters per second and later to bring a light beam to a complete stop, then restart it again.[25]
• Unbreakable hyper-encryption – Michael O. Rabin embedded messages in rapidly moving streams of random digital bits in ways that cannot be decoded, even with unlimited computing power.
• Black silicon – Eric Mazur's group created a new material that efficiently traps light and has potential use in solar cells, global warming sensors and ultra-thin television screens.
• The mathematics of nature – L. Mahadevan and colleagues discovered how the Venus flytrap snaps up its prey in a mere tenth of a second by actively shifting the curved shape of its mouth-like leaves.
• Atmospheric modeling – Loretta J. Mickley, Dan Jacob and colleagues found that the frequency of cold fronts bringing cool, clear air out of Canada during the summer months declined by about 20 percent. These cold fronts are responsible for breaking up the hot, stagnant air that builds up regularly in summer, generating high levels of ground level ozone pollution.
• High speed nanowire circuits – Donhee Ham and Charles Lieber made robust circuits from minuscule nanowires that align themselves on a chip of glass during low-temperature fabrication, creating rudimentary electronic devices that offer performance without high-temperature production or high-priced silicon.
• Double emulsions – A new microfluidics-based device made by David A. Weitz and colleagues at Harvard University and Unilever makes precisely controlled double emulsions in a single step. Double emulsions, or droplets inside droplets, could be useful for encapsulating products such as drugs, cosmetics, or food additives.

• Applied physicist Lene Hau caused a light pulse disappeared from one cold cloud then was retrieved from another cloud nearby. In the process, light was converted into matter then back into light.
• A research team led by Mike Aziz and Earth and Planetary Sciences' Kurt House invented an engineered weathering process that might mitigate climate change.
• Bioengineers including David Edwards collaborated with public health researchers at the Harvard T.H. Chan School of Public Health to develop a novel spray-drying method for delivering a tuberculosis vaccine that could help prevent the related spread of HIV/AIDS in the developing world.
• Working with a team of Dutch researchers and software developers, SEAS computer scientists used a novel peer-to-peer video sharing application to explore a model for e-commerce that uses bandwidth as a global currency.
• Rob Wood's team launched a robotic fly that could be used in everything from surveillance to chemical sensing.
• MIT's Technology Review named the creation of light-focusing optical antennas (that could lead to DVDs that hold hundreds of movies) as one of their Top 10 emerging technologies for 2007.
• Kit Parker's lab found that an elastic film coated with a single layer of cardiac muscle cells can semi-autonomously engage in lifelike gripping, pumping, walking and swimming.
• Nan Sun and Donhee Ham built what may be the smallest complete nuclear magnetic resonance (NMR) system to date in a 0.1-kilogram (0.22 lb) package.[26]
• Engineers and applied physicists demonstrated the first room-temperature electrically pumped semiconductor laser source of terahertz (THz) radiation, also known as T-rays.
• A team composed of Harvard students and alumni was among the winners of the World Bank's Lighting Africa 2008 Development Marketplace competition, held in Accra, Ghana. The innovation, microbial fuel cell-based lighting systems suitable for Sub-Saharan Africa, netted the group a $200,000 prize.[27]
• In collaboration with SiEnergy Systems, materials scientists at SEAS have demonstrated the first macro-scale thin-film solid-oxide fuel cell (SOFC).[28]
• An interdisciplinary research effort investigated digitized text corpuses containing about 4% of all books ever printed in English, between 1800 and 2000. It was co-founded and co-directed by Erez Aiden and Jean-Baptiste Michel, whose prototype was instrumental in creating Google Ngram Viewer.
