Turhan Nejat Veziroğlu. Turhan Nejat Veziroğlu (24 January 1924 – 5 September 2024), sometimes referred to as TN Veziroglu, was a professor emeritus at the University of Miami, and during the 1970s chaired its mechanical engineering department and was its associate dean for research. He was the President of the International Association for Hydrogen Energy and founding editor of the International Journal of Hydrogen Energy. A research center at the University of Niğde, Turkey carries his name.

Early life and education 
Veziroğlu was born and raised in Turkey, where he attended elementary and middle school in Izmir, then attended Pertevniyal High School in Istanbul. After attending Istanbul Technical University for one and a half years, he became a student in England during World War II, receiving a B.Sc. from University of London in 1946, along with an A.C.G.I. in mechanical engineering in London that same year. In 1947, he received the D.I.C. in engineering and technology from the Imperial College of Science and Technology in London. In 1951, Veziroğlu wrote his Ph.D. dissertation at the University of London.

Veziroğlu returned to Turkey after graduating, joining the Turkish military for compulsory military service, in the ordnance section, inventions examiner, from 1952 to 1953. He worked as an engineer and scientific advisor for the Office of Soil Products in Ankara from 1954 to 1956, including as Deputy Director of Steel Silos. He spent a summer working on nuclear engineering at the Electric Power Research Institute in Ankara during 1956. He was an engineering consultant in Istanbul during 1957 and 1958, then worked in his family's business, Veziroğlu Construction Company, as technical director from 1959 to 1961.

Work 
In 1962, Veziroğlu became an associate professor at the University of Miami in Coral Gables, Florida, becoming full professor of mechanical engineering there in 1966, retaining that title through 2009, when he became professor emeritus. He was made a full member of their research faculty in 1969, serving as Director of Graduate Studies from 1965 to 1971, and as chairman of the department of Mechanical Engineering from 1971 through 1975.

Veziroğlu created the first engineering Ph.D program at the university, and in 1974 was organizer of an early conference on hydrogen energy.

He then accepted a visiting professorship to the Middle East Technical University. In 1973, shortly after the energy crisis, Veziroğlu established the Clean Energy Research Institute within the university, and was its director from 1974 onward. He organized a conference on hydrogen energy in 1974. He became Associate Dean for Research in 1975, and maintained that role through 1979. He was a visiting lecturer at Xi'an Jiatong University during the summer of 1980, and a visiting lecturer at the Atomic Research Laboratories in Argentina during the summer of 1985.

As a researcher in hydrogen energy and two-phase flows, Veziroğlu has co-authored over 300 scientific papers, and was a founding editor of the International Journal of Hydrogen Energy. Veziroğlu was also named honorary editor-in-chief of Engineering Science and Technology, The International Journal of Sciences and Engineering: Research and Applications, and International Scientific Journal for Alternative Energy and Ecology.

In his seventies, Veziroğlu took a leave of absence from the University of Miami, becoming founding director of International Centre for Hydrogen Energy Technologies. He returned to his professorship in 2007, and on May 15, 2009 became professor emeritus. In 2010, the 10th International Conference on Clean Energy was dedicated to his work.

He was founding editor of the International Journal of Hydrogen Energy and founder of Hydrogen Energy Publications LLC. He was  president of the International Association for Hydrogen Energy, initiator of the World Hydrogen Energy Conference, and  initiator of the World Hydrogen Technology Convention.
