内容简介：
【数据内容】 A professional genealogy (as opposed to a family genealogy) traces a person's intellectual line of descent via one's PhD advisor or mentor for one's highest non-honorary degree.
The starting points for this Database are usually chemists, so that this is a Chemical genealogy database; some scientists from other disciplines are included as the lines are traced.
The Database contains information about each person's birthdate, deathdate, highest non-honorary degree, degree date, degree place, degree advisor, scientific accomplishments, and references from which the information was compiled.
