V originále

We review the invention of the Delta a photometric system, which provides an efficient method to detect magnetic chemically peculiar stars, but also some other groups such as emission-line or metal-weak objects. Besides the investigation of numerous field stars, the photometric system was also applied to various stellar aggregates, from nearby Galactic open clusters over globular clusters up to field populations and clusters in the Large Magellanic Cloud. The study of star cluster members clearly provides the basis to improve knowledge connected with evolutionary topics. We discuss some results that were made during the four decades long history of Delta a photometry.
