   The meeting is now known as the 1st Texas Symposium on Relativistic Astrophysics. It's an ongoing series of meetings on gravity, cosmology, and relativity that takes place in December of most years.

   The emphasis that first year was on quasi-stellar radio sources, which had been identified a few years earlier. In February of 1963, Maarten Schmidt recognized the Balmer series in their spectra and concluded they were very far away and ultra-luminous.
