Carlos Jaschek

Jaschek directed the Center of Stellar Data (CDS) from 1975 to 1990,

As Director, Jaschek was concerned with improving astronomical naming conventions. In 1979 at an IAU meeting in Canada, over 100 astronomers from 15 Commissions met regarding the designation of objects, and before William P. Bidelman gave the report on their suggested reforms, Carlos Jaschek began to introduce the need for them by saying:

In 1986, he listed the 10 different factors for which a star may be named, noting that the variety was for historical reasons and "It is certainly not very rational to have 10 different practices for the same operation", before suggesting some guidelines.

Jaschek was also interested in the Set of Identifications, Measurements and Bibliography for Astronomical Data (SIMBAD). In addition to working to make the CDS the world's largest astronomical database, Jaschek helped with the creation of astronomical data centers in China, Japan, India, Argentina and the U.S.S.R. They also identified the presence of rare-earth elements in stars of Mn and SrCrEu groups. The Behavior of Chemical Elements in Stars (1995), and Spectroscopic Atlas for the Southern Sky Stars He authored or co-authored ~250 refereed publications and over 15 books

Jaschek was Invited Speaker at ~15 international meetings. He helped organize 14 scientific meetings, and frequently edited or co-edited the proceedings.

In 1993, the Jascheks retired from Strasbourg Observatory.
