L. Dennis Smith (January 18, 1938 – March 29, 2021) was an American scientist and academic administrator who served as the president of the University of Nebraska system from March 1, 1994, to June 2004.

Anthony Atala (born July 14, 1958) is an American
bioengineer, urologist, and pediatric surgeon. He is the W.H. Boyce professor of urology, the founding director of the Wake Forest Institute for Regenerative Medicine, and the chair of the Department of Urology at Wake Forest School of Medicine in North Carolina. His work focuses on the science of regenerative medicine: "a practice that aims to refurbish diseased or damaged tissue using the body's own healthy cells".Dr. Atala is the creator of the first 3D bioprinters (Integrated Tissue and Organ Printing System or ITOP) and is one of the foremost leading figures in the field of organ printing. Atala and his team developed the first lab-grown organ (a bladder) to be implanted into a human. He is also developing experimental technology that can 3D print human tissue on demand.As director of the Wake Forest Institute for Regenerative Medicine, Dr. Atala leads a team of more than 400 researchers dedicated to developing cell therapies and engineering replacement tissues and organs for more than 40 different areas of the body.Dr. Atala is editor of 3 journals and 25 books including Principles of Regenerative Medicine, Foundations of Regenerative Medicine, Methods of Tissue Engineering and Minimally Invasive Urology. He has published over 800 journal articles and has received more than 250 national and international patents. Fifteen technology applications developed in Dr. Atala's laboratory have been used clinically.He serves on the editorial board of the scientific journal Rejuvenation Research, on the national board of advisors for High Point University and on the SENS Research Foundation's research advisory board. He is a founding member of the Tissue Engineering and Regenerative Medicine International Society (TERMIS) from which he received the Lifetime Achievement Award. Atala is the director of the Armed Forces Institute of Regenerative Medicine, a federally funded institute created to apply regenerative medicine.

Ambrosius Arnold Willem Hubrecht (2 March 1853, in Rotterdam – 21 March 1915, in Utrecht) was a Dutch zoologist.
Hubrecht studied zoology at Utrecht University with Harting and Donders, for periods joining Selenka in Leiden and later Erlangen, and Gegenbauer in Heidelberg. He graduated magna cum laude with Harting in 1874 with a study on nemertine worms. In 1875–1882 he worked at the Rijksmuseum van Natuurlijke Historie in Leiden, where he was the curator of ichthyology and herpetology, and in 1882 became professor at Utrecht. In 1890–1891 he traveled in Java, Sumatra, and Borneo, where he made embryological studies, notably on the tarsier. He visited the United States in 1896 and 1907. Honorary degrees were conferred on him by Princeton University, the University of St Andrews, the University of Dublin, the University of Glasgow (LL.D 1901), and the University of Giessen.
Hubrecht´s most important work was in embryology and placentation of the mammals. In papers in the Quarterly Journal of Microscopial Science in 1883 and 1887 he put forth the theory—also held by Sir E. Ray Lankester—that the vertebrates originated in a Nemertine form, basing this on his discovery in the Nemertines of a continuous nerve sheath. The Descent of the Primates (1897) is the title under which were published his lectures at the sesquicentennial celebration at Princeton.
In 1883 he became member of the Royal Netherlands Academy of Arts and Sciences. Hubrecht founded the Institut Internationale d'Embryologie, today known as the International Society of Developmental Biologists.
