Alfred Einhorn

Alfred Einhorn was a German chemist most notable for first synthesizing procaine in 1905 which he patented under the name Novocain. Until that time the primary anesthetic in use was cocaine, however its undesirable side effects led scientists to seek out newer anesthetic drugs. Novocain was found to be comparatively safe and effective, although its anesthetic effects were weaker than cocaine and some patients proved highly allergic. However, none of the other anesthetics developed during this period proved more effective and Novocain quickly became the standard local anesthesia. Although its use has largely been replaced by lidocaine, it is still in use today, most frequently in dentistry.
