With about 36,500 students from about 130 nations, Johannes Gutenberg University Mainz (JGU) is one of the ten largest universities in Germany. As the only comprehensive university in Rhineland-Palatinate, JGU combines almost all academic disciplines under one roof, including the Mainz University Medical Center, the School of Music, and the Mainz Academy of Arts. This is a unique feature in the German academic landscape. With 84 fields of study and a total of 222 degree courses, including 98 Bachelor’s and 103 Master’s degree programs, JGU offers an extraordinarily broad range of courses. Some 4,150 academics, including 540 professors, teach and conduct research in JGU's more than 150 departments, institutes, and clinics (as of December 1, 2011; financed by federal and third-party funding). JGU is a globally renowned research university of national and international recognition. This reputation comes thanks its outstanding individual researchers as well as extraordinary research achievements in the field of particle and hadron physics, materials sciences, earth system sciences, translational medicine, the life sciences, media disciplines, and historical cultural studies. JGU’s scientific prowess has been affirmed by its success in the Excellence Initiative by the German federal and state governments to promote top-level research at German universities: Mainz University is one of 23 universities in Germany that have received approval for a so-called Cluster of Excellence as well as approval for a Graduate School of Excellence. The Cluster of Excellence on "Precision Physics, Fundamental Interactions and Structure of Matter" (PRISMA), which is primarily a collaboration between particle and hadron physicists, and the Graduate School of Excellence "MAterials Science IN MainZ" (MAINZ) are considered among the elite research groups worldwide. These two projects will receive financing to the tune of EUR 50 million by 2017. The university's good positions in national and international rankings and the award of numerous research prizes are further confirmation of the importance and success of the research being conducted by JGU-based academics. This success has been made possible in part through the unique large-scale research equipment available at Mainz University, such as the TRIGA light water research reactor and the MAMI electron accelerator, which both attract researchers from around the world. The research-oriented teaching – with targeted and early integration of research content into the curriculum – is another key element of the JGU philosophy. JGU is the sole German university of this size to combine almost all institutes on one campus, while also housing four partner research institutions that conduct cutting-edge research outside the organizational structure of the university itself. There are also on-campus student dormitories and childcare facilities. The clinical and clinical/theory institutes of the Mainz University Medical Center are located within roughly one kilometer of the campus. JGU lives the notion of a civic university being an integral part of society and collaborating with the community it is part of. This means that it also provides lifelong learning programs and promotes timely and comprehensive knowledge and technology transfer. Founded in 1477 during the era of Johannes Gutenberg and reopened after a 150-year break in 1946 by the French forces then based in Germany, Johannes Gutenberg University Mainz owes much to the man whose name it bears and his achievements. With his achievements in mind, the university strives to promote and implement innovative ideas, to help improve people’s living conditions through knowledge, to facilitate their access to education and science, and to encourage people to transcend the many restraints that they encounter on a daily basis. This is the mission that Johannes Gutenberg University Mainz has set itself.
