The Somogyi hypothesis: a parallelism with Michael Somogyi's life.

Michael Somogyi (Somogyi Mihály, 1883-1971) was a Hungarian biochemist who developed his scientific career in Europe and, primarily, the United States. He gave the name to the eponymous Somogyi effect or Somogyi hypothesis (in short, rebound hyperglycemia after insulin-induced hypoglycemia, particularly nocturnal), which was an axiom in the treatment of diabetes for decades. Although it is currently debated whether the Somogyi hypothesis is a real or relevant phenomenon in patients with diabetes, Somogyi's other significant career achievements are often overlooked. The aim of this historical note is to compile and highlight Michael Somogyi's scientific achievements. Michael Somogyi was a pioneer in the administration of insulin to patients with diabetes in the United States and in devising a method for insulin production. In addition, he highlighted the relevance of diet in patients with diabetes and was one of the first chemists to be integrated into clinical laboratories. There, Somogyi standardized long-lasting biological determinations, such as that of amylase, and he was one of the first scientists to combine basic research (from his training as a biochemist) with clinical research in close collaboration with physicians caring for patients, which is what we know today as translational research. Notably, the trajectory of his scientific career resembles the rebound effect of Somogyi's hypothesis: after reaching a low point of work activity well below his professional qualifications, his effort and tenacity led to the aforementioned achievements, and he became part of the history of hypoglycemia and diabetes.
