Stephan A. Fagerquist

October 26, 1957 ~ April 17, 2020 (age 62)


It is with great sorrow that the family of Stephan Fagerquist announces his sudden passing on April 17, 2020 in Nashua, New Hampshire.

Stephan A. Fagerquist was born October 26, 1957, in Worcester, Massachusetts to Harry Walter Jr. and Carole (Clifford) Fagerquist. Steve grew up in Winthrop and Acton, Massachusetts, and later Aruba where he graduated from Colegio Arubano high school as valedictorian. 
He earned bachelor of arts degrees in German and Political Science from the University of New Mexico in Albuquerque in 1979.  He went on to earn his Masters in Business Administration from Boston University in 1997 with high honors. Steve served in the U.S. Navy from 1979-1987. He then served in the U.S. Navy Reserve until his retirement in 1994 as a Lieutenant Commander. Steve worked at Teradyne from 1989 until 2018 when he retired as VP of Human Resources. He was well liked at the company and made many close friends during his time there.

Steve’s military service and his work at Teradyne allowed him to travel the world and live abroad with his family in Gaeta, Italy; Munich, Germany; and Shanghai, China. Steve continued traveling, making many trips to California to soak up the sunshine with his daughter, Kasey; to Virginia to enjoy time with his son, Keith; and to Chicago to visit his close companion, Lisa.

Steve and his wife, Heidi, amicably divorced in 2015 but continued to be friends the remainder of his life.

Steve’s many interests included history, especially the American Civil War, politics, and genealogy; taking pride in documenting his family history through photos and videos.  An avid sports fan, he organized, coached, and played on an “over 40” baseball team, The Nashua Tigers, for many years. He loved painting and found inspiration from many places but especially in the scenic beauty of New England. He spent countless hours in galleries discussing art with his daughter, Kasey. He enjoyed a wide range of music from classical to the Beatles and was dedicated to playing the acoustic guitar the majority of his life. A passion he passed down to his son, Keith.

The Wyakin Foundation was an important part of his life. He volunteered much of his time and expertise to the foundation, mentoring severely wounded veterans to help prepare them for successful post-military careers. His thoughtful guidance with the Wyakin Warriors and their families was inspiring, and he forged a strong and everlasting bond with so many of them.     

He is survived by his daughter Kathryn “Kasey” Fagerquist of Los Angeles, California; son Keith of Alexandria, Virginia; his companion Lisa Buesser and her daughter Kylie both of Center Tuftonboro, New Hampshire and Chicago, Illinois; former wife Heidi F. Hatfield and mother-in-law Dr. Susan Hatfield, both of Sioux City, Iowa; brothers and sisters-in-law Bill and Patsy Fagerquist of Port Jefferson, New York; Rob Fagerquist of Perryville, Alaska; and Harry "Bud" and Misako Fagerquist of Canton, Michigan; aunt, Linda Fagerquist of Kingwood, Texas; nephews Joseph and Nicholas Fagerquist; niece Emily Fagerquist, and a host of friends and relatives.

A Celebration of Life and final resting at Arlington National Cemetery will be scheduled at a later date.
