The Thomas G. Fowler Collection

 

Thomas Fowler, of Stamford Connecticut, was a mineral enthusiast, an avid outdoorsman throughout his lifetime (1943-2006), and the President of an internationally recognized design firm.  He was an active field collector of minerals and member of the Stamford Mineralogical Society during the 1960’s and 70’s.  His primary area of interest was in the minerals of South Africa of which he built a fine collection in both depth and breadth.  His Tsumeb suite numbered approximately 1,500 specimens, many of which are exemplary: dioptase, cerussite, and smithsonite are examples of

species of which he had many top pieces.
