Kenneth Daniel Allen

Kenneth Daniel Allen, son of Gertrude Hanley Allen and Kenneth Joseph Allen, was born in Baltimore, Maryland on June 8, 1927, and passed away peacefully on March 5, 2026, at the age of 98. He lived a remarkable life marked by curiosity, innovation, humor, patriotism, and devotion to family.

Ken graduated from the Baltimore Polytechnic Institute in 1945 and served in the U.S. Navy during World War II after studying electronics. He later earned his engineering degree from the University of Maryland in 1950 and went on to a distinguished career in aerospace, defense systems, computers, and medical technology.

Throughout his career, Ken worked on pioneering projects involving strategic air defense, navigation systems, aerospace computing, and early minicomputer development. He contributed to programs connected with the B-36 bomber, NORAD, missile guidance systems, biomedical monitoring, and emerging healthcare technologies. He was also an entrepreneur and helped launch several successful technology companies, including Microgenics and Microdata Corporation.

In 1954, Ken married Doris Mae Gern, the love of his life and devoted partner for 62 years. Together they built a warm and adventurous life centered on family, travel, faith, and hospitality. Their home in Tustin, California, became a gathering place for friends and students from around the world, and countless celebrations. Doris preceded him in death, but Ken often spoke with gratitude for their years together.

Ken was known for his quick wit, storytelling, enthusiasm, and larger-than-life personality. He loved playing bridge, history, engineering, sailing, and spirited conversation. Even in his later years, he remained intellectually engaged and optimistic about the future of science and medicine.

He is survived by his four children—Karen Kempf, Marcia Robison, Teresa Allen, and Steven Allen—his grandchildren, Pamela and Marian, his great-grandchildren, Bowie and Rumi, his brother, John Allen (pre-deceased by brother Frank), as well as extended family and many friends whose lives he touched with generosity, humor, and encouragement.

Ken Allen’s long and adventurous life reflected the extraordinary changes of the twentieth century, and he embraced them all with energy, imagination, and determination. He will be deeply missed and lovingly remembered.
