The Woods Hole Oceanographic Institution announces with great sorrow the death of former MIT-WHOI Joint Program Student Douglas R. Mook of Hollis, NH, on October 18, after a long battle with a rare neurological disorder. He was 67.

Doug was  born on July 17, 1952 in Englewood, NJ, son of Bob and Connie (Verheyden) Mook.

Doug graduated from high school in New Brunswick, NJ. He continued on to MIT where he earned his SB, SM, and EE degrees. He then went on to earn his ScD in Electrical Engineering and Ocean Engineering from the MIT-WHOI Joint Program in 1983. This collaboration allowed him to be at MIT during the school year and spend his summers at the Cape in Woods Hole. Doug felt this was a dream come true as he was able to combine his love of learning with his passion for the ocean.

In his spare time, Doug enjoyed windsurfing, sailing, biking, swimming, and walking in the woods. He also loved music, reading, and spending quality time with friends and family. He was brilliant but down to earth, known for his sense of humor, kind heart, and infectious laugh.

In his professional life, Doug was a problem solver who excelled at adapting technology to help people. He was co-founder and president of The Aptec Group from 2001 until his retirement in 2013. Previously, he ran the ASW division, advanced systems, advanced technology, and signal processing organizations within Sanders/Lockheed Martin from 1984 to 1999, and served as the COO and VP of Engineering at TechOnLine. Doug also served on the Board of Directors for many technology companies.

He was the husband of Julie (Hanson) Mook. Along with his beloved wife of 35 years, he is survived by his son, Kevin Mook of Watertown, Mass; daughter and son-in-law, Kim McDonald and husband Andrew of Chicago, IL; his granddaughter, who will arrive in the near future; his sister and brother-in-law, Carolyn Nagle and husband John III of Hollis, NH; and his nephew, John Nagle IV of Hoboken, NJ.

A memorial visitation will be held on Wednesday, October 23, from 4-6 p.m., at Davis Funeral Home, One Lock Street in Nashua, NH. Interment will be held privately at East Cemetery in Hollis, NH.
