Extract

Who discovered QSOs? What was the first QSO discovered? To Maarten Schmidt (1963) goes the credit for realising that the emission lines he saw in a 13 mag star were the Balmer series in hydrogen at a redshift of 0.158. The first QSO had been recognised. But discovery is a complex process. Schmidt observed the ‘star’ because it was associated with a radio source 3C 273 by means of an accurate radio position. This was the first of several instances where accurate radio positions have enabled significant progress in the QSO story.
