- Named for Egbert Adriaan Kreiken (November 1, 1896 - August 16, 1964), a Dutch teacher and astronomer. For most of his life he served as an educator, working in the developing countries of Indonesia, Liberia, and Turkey. Over a forty year career he would publish a number of papers on astronomy, including studies of stars and stellar systems.
- This name appears on LTO-81C1 (for which it served as the chart title). It does not appear to replace any previous IAU-approved designation. Although it appears in the cumulative list of approved names printed in IAU Transactions XVB, when and how it came to be approved is not entirely clear from the IAU record. Biographical information was unofficially reported in Ashbrook, 1974. - Jim Mosher
