87 Years of Inspiration
For out of olde feldes, as men seith,
Cometh al this newe corn fro yeer to yeer;And out of olde bokes, in good feith,
Cometh all this newe science that men lere.Geoffrey Chaucer
ca. 1340–1400, The Parlement of Foules
This celebrates the extraordinary life of John Sinkankas, who passed away on May 17th, 2002 at his San Diego home, after a brief illness.
All of us in the industry are better professionals because of John’s words and work. His love of the earth has produced volumes of insight, scientific knowledge and wisdom. So we take time to honor this remarkable individual.

Born on May 15, 1915 in Patterson, New Jersey, John Sinkankas began his life-long love affair with minerals at age seven in the famous traprock quarries near his home.
After a 25-year career as a flyer with the US Navy, during which he rose to the rank of Captain, he devoted himself to his passion – rocks, minerals and gems. His first book on the subject was published in 1955 and since that time he has published 14 others.
In addition to his writing and flying, John was also a talented artist, with his watercolors featured in a number of his books. Two fine examples of his watercolors are featured in these pages.
The various titles John earned or was honored with over his long career would fill several pages, but a few are worth noting:
- 1982 – Doctor of Philosophy, Honoris Causia, William Patterson College
- 1984 – A new phosphate mineral was named sinkankasite in his honor
- 1985 – Honorary membership in the Rochester (NY) Academy of Sciences
- 1988 – Awarded the first individual Carnegie Mineralogical Award
Pilot, author, bibliophile, bookbinder, collector, artist, lapidary, historian, scholar – John Sinkankas was the epitome of the Renaissance man.

A Family Affair
On February 5, 1940, then Ensign John Sinkankas married his college sweetheart, Marjorie Jane McMichael in Key West, Florida. Thus began one of the most successful partnerships in the field of gems and minerals.
John and his wife, Marjorie, have long shared a love of books. Together, they operated Peri Lithon Books, one of the country’s finest dealers in antiquarian books on the earth sciences.
In 1988, their personal collection of over 13,000 items – more than 40 years in the making – was acquired by the Gemological Institute of America and today forms the foundation of the Richard T. Liddicoat Library.
John is survived by his wife, Marjorie, and their four children: John William, Seattle, WA, George Martin, Knoxville, TN, Sharon Jane Tooley, San Diego, and Marjorie Ellen Coates, Atlanta, GA. They have also been graced by six grandchildren.
