William Weise, of Springfield Virginia, passed away peacefully on Tuesday, March 11, 2025, surrounded by loved ones—just one day after celebrating his 96th birthday. Born on March 10, 1929, in Philadelphia, Pennsylvania, to George and Georgia (Thorburn) Weise, William was a graduate of Temple University and later Arizona State University. He enlisted into the Marine Corps on October 16th, 1951, and retired on August 31st, 1982, serving nearly 31 years in the U.S. Marine Corps, including the Korean and Vietnam Wars. In Vietnam, he took command of the 2nd Battalion, 4th Marines (2/4)—the “Magnificent Bastards”—in 1967. In the Spring of 1968, he led 2/4 through the fierce Battle of Dai Do where, despite being wounded multiple times, he pressed on to rally his troops. For his valor, he received the Navy Cross, the Silver Star, two Legions of Merit (one with a Combat “V”), three Purple Hearts, and the Vietnamese Cross of Gallantry, among other honors. His career began and concluded at Parris Island, South Carolina, bookending his service in the U.S. Marine Corps. After retiring, William and his wife Ethel spent several years on the open road in a truck and trailer, visiting family, friends and multiple National Parks & Forests while enjoying each other’s company. Later William played a key role in establishing the 2/4 Association and the National Museum of the Marine Corps. He served on the boards helping to raise funds and shape their vision, leaving a lasting tribute to his fellow Marines. William was a dedicated husband, father, grandfather, great-grandfather and friend to many, with Christ as his foundation.

William was preceded in death by his beloved wife of 42 years, Ethel (Jaeschke) Weise, and his siblings: older brother George “Skip” Weise, older sister Marjorie “Midge” Miller, and younger brother John “Jack” Weise, a retired Episcopal priest. He leaves behind a proud legacy in his children: Carol Olsen (Kenneth), Marc Weise (Lorri), and Holly Michaels; his grandchildren: Matthew Olsen, Amanda Martin (James), Luke Olsen (Philippa), Zane Olsen, Eric Weise, Bri Weise, Samantha Wagstaff, Patrick Wagstaff (Susan), and Timothy Weise; and his great-grandchildren: Randi Martin, Piper Martin, Charlotte Olsen, Emma Olsen, Sarah Lamb, Richard Lamb, Henry Lamb, Hannah Lamb, Rebekah Lamb, Abigail Lamb, and George Lamb.

Celebration of life and graveside services will be announced soon, with details to follow. In lieu of flowers the family request donations be made to the following: The Navy-Marine Corps Relief Society, The Marine Corps Heritage Foundation, The Falls Church Anglican, The Leadership Institute, and Shriners Children’s Hospital.
