Theodric Romeyn Beck (April 11, 1791 – November 19, 1855), alternatively Theodoric Romeyn Beck or T. Romeyn Beck, was an American physician in Albany, New York, specializing in medical jurisprudence who authored the first significant American book on forensic medicine, Elements of Medical Jurisprudence in 1823.
In 1823, while secretary of the Society for the Promotion of Useful Arts (SPUA), he founded the Albany Lyceum of Natural History, which focused on the preservation of mineral and botanical specimens collected in New York state surveys. The following year, SPUA and the Albany Lyceum of Natural History merged to form the Albany Institute; Stephen Van Rensselaer III was appointed its president and Beck was appointed its vice president. He was chosen president of the New York State Medical Society in 1829, and became a manager of the state lunatic asylum before becoming president of the Board of Managers in 1854. During his service, he collected statistics on deaf-mutes, which influenced the legislature to pass laws for the education of the mentally ill. In addition, from 1849 to 1853 he edited the American Journal of Insanity.
His principal work was Elements of Medical Jurisprudence. His brother John Brodhead Beck, also a physician, contributed the material on infanticide. The first edition was printed in 1823, a seventh edition was issued in London in 1842, with notes by Dunlap and Darwell, and a tenth in Albany in 1850.
Beck also contributed to numerous scientific journals. Another of his brothers, Lewis Caleb Beck, wrote a noted book on the Mineralogy of New York (1842).
