Historical Pioneers and the Discovery of X-Rays

• William Crookes:

  • In the 1870s, invented the evacuated glass Crookes tube.

  • The Crookes tube served as the direct precursor to the modern X-ray tube by converting high-voltage electrical energy into diagnostic X-radiation.

• Dr. Arthur Goodspeed and William Jennings:

  • In 1890, produced the earliest known radiographic shadow image ($14+$ X-ray image) during a physics demonstration at the University of Pennsylvania.

  • The image accidentally captured two coins resting on photographic plates exposed to a glowing Crookes tube; they failed to comprehend the physical significance of their finding until after Roentgen's published work.

• Wilhelm Conrad Roentgen:

  • Accidentally discovered X-rays on November 8, 1895, in Germany while experimenting with Crookes tubes.

  • Produced the world's first formal radiograph, capturing the skeletal structure of his wife's hand.

  • Awarded the inaugural Nobel Prize in Physics in 1901.

• Thomas Edison:

  • Invented the fluoroscopic screen, introducing real-time dynamic X-ray imaging.

  • Edison halted all radiation experimentation after his chief assistant, Clarence Dally, died from severe occupational radiation exposure.

• Ed Jerman:

  • Recognized as the Father of Modern Radiologic Technology.

  • Authored the first textbook on radiologic technology, established the first formal educational curriculum, and founded the American Society of Radiologic Technologists (ASRT).

• Emil Grubbe:

  • Developed the first therapeutic application of ionizing radiation.

  • Became the first practitioner to treat breast cancer using targeted radiation therapy.

• Marie Curie and Henri Becquerel:

  • Conducted groundbreaking research on natural radioactivity, winning Nobel Prizes for their discoveries.

  • Curie isolated the radioactive elements polonium and radium.

  • Curie engineered and deployed over $13$ mobile X-ray units ("little Curies") to assist field surgeons during World War I; recognized as the mother of modern physics.

Overview of Radiologic Technology and Certification
