My presentation delves deep into the overlooked contributions of Arthur Eichengrün, a Jewish chemist, to the invention of Aspirin. Despite his instrumental role in the synthesis of acetylsalicylic acid (ASA), Eichengrün’s legacy has been sorely discredited and dismissed by historical revisionism influenced by Nazi rule. Walter Sneader’s research challenges the modern canon, shedding light on Eichengrün’s essential role in ASA’s creation and the consequential erasure of his achievements. The quest to uncover the truth behind Aspirin’s origins reflects broader themes of unseen history and the continual pursuit of knowledge. Bayer’s archive itself holds tantalizing secrets, including Eichengrün’s sealed letter, suggesting a deeper understanding of his contributions awaits discovery. This presentation pleads for a reevaluation of history, advocating for the recognition of Eichengrün’s rightful place in the history books of scientific discoveries.
