Albert Abrams (December 8, 1863 – January 13, 1924) was a controversial American physician, well known during his life for inventing machines, such as the "Oscilloclast" and the "Radioclast", which he falsely claimed could diagnose and cure almost any disease. These claims were challenged from the outset. Towards the end of his life, and again shortly after his death, many of his machines and conclusions were demonstrated to be intentionally deceptive or false.
