Didier (Dana) Addison White of Middletown, Del., formerly of Montclair, died on June 30 at his home, surrounded by family, after fighting courageously throughout his battle with cancer. He was 69.

Mr. White was born in Port of Spain, Trinidad, to Rosanna Lynch (White) and Nellis Noel.  He later lived in Boston, and following his graduation from Danvers High School, he attended and graduated from Boston College, receiving a bachelor’s degree in political science.

He worked as a sales and account representative for several technology companies before leaving the private sector to pursue his interest in teaching in the public schools of Montclair.

Mr. White served as a mathematics and science teacher in an alternative high school program.

Later, he was a beloved technology teacher and guidance counselor at the Mount Hebron Middle School.

Mr. White was deeply committed to service and found many ways to contribute to the betterment of the Montclair community.  He was a member of the Eureka Masonic Lodge in Montclair; served as a valued coach and coordinator for the Montclair Robotics Competition; was a district leader for the Montclair Democratic Committee; and served as treasurer of First Montclair House.

Mr. White was an avid sailor and enjoyed sailing the Long Island Sound with friends and colleagues.   As a knowledgeable art collector he enjoyed visiting galleries and attending art shows, and he became a patron of renowned African and African American artists and developed an impressive art collection.

Mr. White leaves behind the love of his life, Diane (Satterfield), his wife  of 31 years; three sisters, Laurian (Bob) of St. Croix, Beverly of  Denton, Texas, and Marcia of N.Y.C.; a brother, Euyen, of N.Y.C., and a host of nephews, nieces and extended family.

Over the years, Mr. White accumulated a vast network of dear friends from Boston College, from his work in public education and from his involvement in community service.  The list is too long to include here, but the cherished friendships were valued by Didier throughout the years.
