Bash, Frank N. He was a noted observational astronomer whose career was divided between South Africa and Texas.
He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory".

Knox Shaw were the entire staff after R. Redman left, and they aluminized and installed the mirrors in the inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape.
The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. Gold presented David's paper on lunar occultation angular diameters at the January meeting of the Royal Astronomical Society.
For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed.
