D. Y. Liu (劉德勇)

Identity Snapshot

劉德勇 served on the church-building delegation of the Washington D.C. Taiwanese church community: per the memoir 217. 我參與了華府教會的建堂 (陳明賢), he joined 王能祥、蔡武男、凌光雄、王偉國長老 and the author in negotiations with 世界和平協會董事長王清珠女士, which secured a donation of three plots of land and cash split between the church and Bethesda長老教會 (the Rockville plot later rose sharply in value through urban renewal).
He also supported the community’s historical record: per 270. 早期留學北美的台灣女士–戰後初期 (朱真一), 柯大闢博士、劉德勇博士及劉克全先生 donated reference works to the project — 《蕭安居牧師-生平及其家譜》《春風化雨》《永遠的劉瑞山》.
Linked in the church memoir alongside 陳建南 and 凌光雄 as part of the early D.C. Taiwanese church network.
