. Annis brought on as Chairman of the Board of Directors, Bruno Rossi, PhD, of Bruno Rossi of MIT to help guide their efforts. Rossi had earlier confirmed the existence of cosmic rays, and postulated that black holes would emit tremendous bursts of cosmic radiation as they swallowed celestial objects. At the urging of Rossi, Annis brought on board

Riccardo Giacconi Riccardo Giacconi ( , ; October 6, 1931 – December 9, 2018) was an Italian-American Nobel Prize-winning astrophysicist who laid down the foundations of X-ray astronomy. He was a professor at the Johns Hopkins University. Biography Born in ...

As a consultant to American Science and Engineering, Inc., Rossi initiated the rocket experiments that discovered the first extra-solar source of X-rays, Scorpius X-1. Despite Rossi's pivotal discoveries and work in this area, in 2002 Richardo Giacconi alone won the Nobel Prize for its discovery and invention

(equipped with the first full imaging X-ray telescope on board a satellite, launched in 1978). Throughout his tenure as president of AS&E (from its inception in 1958 until he left in 1993), Annis was a leading inventor/scientist for the company, including inventing the backscatter technology, which enabled the detection of plastic explosives, he also invented the body scanner, originally developed as a machine to detect contraband in/on people for prisons, but later adopted for use in airports. Body scanners are now standard as part of pre-boarding security screenings in airports around the world. AS&E also produced the first 4th generation CT scanner for commercial use in 1976

The development of focusing optics for soft X-rays led also to rocket-borne solar observations, the later
