'''Razdow Laboratories''', Inc. was founded by [[Austria]]n born physicist Dr. Adolph Razdow (1908–1985). A refugee of the Holocaust, he emigrated to the United States in July 1946. In the early 1960s Razdow was awarded a contract by [[NASA]] to develop and deploy a series of solar monitoring telescopes at major observatories around the globe. These devices automatically tracked the [[Sun]] across the sky, recording and transmitting television images of the solar disk in the [[Hydrogen-alpha]] spectrum.<ref>{{cite journal|last1=Hennessey|first1=J.
