Dr. Edward E. David, Jr. was Science Advisor to President Nixon and Director of the White House Office of Science and Technology from 1970 to 1973.

He has also served as President of Exxon Research and Engineering Company from 1977 to 1986, and as Executive Director of Bell Telephone Laboratories from 1950 to 1970.  He is a past president of the American Association for the Advancement of Science, and was the U.S. representative to the NATO Science Committee for 16 years.

He received his doctorate in engineering from MIT.

In 1993 he sold a large portion of his "first collection" to the Houston Museum of Natural Science, where it forms the core of a major hall. He then began building yet another major collection - his "second collection," which he also sold in recent years. The specimens on this page are from his second collection. Although in his eighties, Dr. David, as you would expect, is now building yet another collection.

I have always admired Dr. David's eye for aesthetics and I am happy to present some of the fine specimens from his second collection. And, there will be more from his collection in a future update.

Take a Virtual Tour of the Sterling Hill Mining Museum

Absolutely stunning coverage of gemmy, double terminated Fluorapophyllite crystals with some white Stilbite on a Choral (fine Quartz) covered matrix. In super condition. This one ranks on the upper echelon of Indian specimens.
Large cluster of glassy Calcite crystals from the Bigrigg Mine in England.
Well crystallized, silvery Galena on matrix from the now closed Turt Mine in Romania.
Excellent specimen of Hemimorphite from the Sterling Hill, which was the source for most of the local (New Jersey) Hemimorphite. The bulk of the material was found in the old Passaic and Noble Mines. On many specimens the terminations of the Hemimorphite crystals are serrated and closely-spaced. Collectively the crystals resemble aggregates of maggots, from which rose the old miner’s name, "maggot-ore". These specimens are among the best Hemimorphite specimens found anywhere and are present in most systematic collections.  Most are white, lustrous, and very attractive and some have interesting depositional stains. The occurrence was mined extensively in the 1870’s, and Hemimorphite was at that time a chief ore of zinc from Sterling Hill.
