Woldemar Ludwig Grenser (2 January 1812, Dresden-Neustadt - 2 June 1872, Dresden) was a German obstetrician.
From 1830 he studied medicine at the University of Leipzig, obtaining his doctorate in 1838 with a dissertation titled Latin: De vi puerperii lactandique temporis medication trice. In 1839 he took a scientific journey, visiting Prague, Vienna, Paris, London, Würzburg and Heidelberg.[1] In 1843 he became an associate professor of obstetrics at the University of Leipzig, and two years later relocated to Dresden as professor of obstetrics at the medical-surgical academy and director of the maternity institute.
In 1856 he was appointed Königlich Sächsischen Hofrat (Royal Saxon Court Councilor), and in 1864 became Geheimen Medizinalrat (Privy Medical Councilor).
Among his written works was an edition of Friedrich August von Ammon's Die ersten Mutterpflichten und die erste Kindespflege (1864), and with Hermann Franz Naegele (1801–1851), was co-author of Traité pratique de l'art des accouchements.[2] He also posthumously continued work on Naegele's Lehrbuch der Geburtshilfe (Textbook of Obstetrics).[3] Other noted works by Grenser include:
In 1846 with Carl Friedrich Haase (1788-1865), he successfully treated future writer Karl May (1842-1912) for visual impairment.[4]
