A 2% silver nitrate solution applied to the eyes of newborns immediately after birth transformed neonatal care in the late nineteenth century. Carl Siegmund Franz Credé introduced this intervention to prevent ophthalmia neonatorum, a condition that previously accounted for half of all blindness across Europe. This medical innovation effectively reduced infant infection rates to 0.15% during his clinical trials.
Academic and Clinical Career
Born in Berlin in 1819, Credé pursued a career in medicine, receiving his doctorate from the University of Berlin in 1842. His institutional work expanded significantly in 1852 when he assumed the roles of director at the Berlin School of Midwives and chief physician at the Charité maternity division. Later, his professional life centered at Leipzig University, where he served as a professor of obstetrics and director of the maternity hospital. During his tenure in both Berlin and Leipzig, he established specialized out-patient clinics focused on gynecology.

Credé developed specific medical procedures that became standard practice in obstetrics. Beyond the prophylaxis for neonatal conjunctivitis, he implemented a manual technique to hasten the delivery of the placenta, which is now referred to as Credé's manoeuvre. His work extended to the care of premature infants, as documented in his 1884 treatise regarding warming devices for feeble newborns. He also contributed to the dissemination of medical knowledge by editing the Monatsschrift für Geburtskunde from 1853 to 1869, followed by the Archiv für Gynäkologie starting in 1870.
Scientific Documentation and Legacy
His research findings were published in significant clinical texts, including the two-volume Klinische Vorträge über Geburtshilfe released in Berlin between 1853 and 1854. His 1884 publication, Die Verhütung der Augenentzündung der Neugeborenen, detailed his findings on the use of silver nitrate. By the time of his death in Leipzig in 1892, Credé had influenced a generation of practitioners, including his student Johann Friedrich Ahlfeld. His family connections included his son, the surgeon Benno Credé, and his son-in-law, the gynecologist Christian Gerhard Leopold.
