Ivan William Buddenhagen was born in Ventura, Calif., in 1930 to Harold J. Buddenhagen, a petroleum geologist, and Pearl M. Buddenhagen, a teacher and homemaker. He died at his Davis, Calif., home on July 9, 2022. He would have approved of his simple coffin, crafted of pine that had been felled by drought and beetles, and adorned with messages and drawings from his beloved family. A sprawling bouquet of his favorite plants, including banana, served as a botanical mantle atop his coffin.
