ASTRO's roots date back slightly more than a half-century. It all began in the mid-1950s, when America's radiotherapists started gathering at a Chicago restaurant each November or December while attending the annual meeting of the Radiological Society of North America (RSNA). In 1955, some of the most important people practicing radiation therapy in the United States met at Barney's Market Club on Randolph Street. Thus was formed the nucleus for what would become the largest and most influential society of radiation oncologists in the world.
