With great sadness, I must report the passing of my father-in-law exactly one month after his 95th birthday. Bob often insisted that he would live to be one-hundred-and-eleven, and I wondered if he might. Aged as the retired engineer might be, he exhibited surprising vigor and sharp intellect. I will miss the gentle geek, who continually searched for ways to mature his spirit and improve—extend—his livelihood. If only more people, of any age, opened their minds to new ideas rather than crusting over into immutability.

On Oct. 15, 2007, my family relocated to San Diego to be closer to him, understanding that the solitary elderly rarely receive the respect they deserve. Someone in so-called official capacity would have placed Bob in an institution long ago, because of his age. But with a little assistance—our apartment is one block from his—he lived independently up until the end, passing in his own bed. I am especially proud of my wife for being such a dutiful daughter. Anne enabled her dad.
