"I realized I had been trained all my life to cure disease. Death was an enemy," Foster said at the time. "I had never had any training on how to cooperate with disease."
He said that because of his experience, he began to give lectures about end-of-life care and treatment. Then a friend asked to put some of his thoughts into brochures, which evolved into his book, which he and his wife published.
"I kept getting asked to do more and more talks, because of my dad. I was chairman of ethics at Thomas, and I made up my mind they needed an end-of-life team, and I got the administration to OK that," Foster said in 2004.
In 2011, HospiceCare opened an inpatient unit at Thomas Memorial Hospital. At that time, a Thomas Memorial official lauded the hospital's palliative care and said Foster "is so passionate about end-of-life care."
Jon and Betty Walker both said that Bruce Foster's wife had been an office manager at his medical practice, but she had not been working there lately.
The Walkers said the Fosters were great neighbors.
"They were perfect neighbors, honestly," Jon Walker said. But he added, "As much as they were nice, they were also very private."
Betty Walker added: "Bruce was very sociable. She kept to herself."
Still, the Walkers both said that it was clear to them that the Fosters were very close, never fought or yelled at each other and were by each other's side constantly.
Jon Walker described Bruce Foster as a nice, "super bright, [and] really intellectual-type guy."
Betty Walker said she knew of "not an instance of violence between the two. They were best friends."
