Ajahn Sumedho was born Robert Karr Jackman in Seattle in 1934 and raised in an American Christian family, a documented American origin distinct from the Thai forest institution building his first article covers. At eighteen he served four years as a United States Navy medic during the Korean War, then completed a bachelor's degree in Far Eastern Studies and, in 1963, a Master's degree in South Asian Studies at the University of California, Berkeley, a documented course of military and academic training distinct from anything in the account of Wat Pah Nanachat or Chithurst his first article traces.
After a year as a Red Cross social worker, Jackman served in the Peace Corps as an English teacher in Borneo from 1964 to 1966, a documented overseas posting distinct from the deliberate monastic translation project his first article credits him with leading in Thailand and then England. Only after that posting did he travel to northeast Thailand, where he was ordained a novice at Wat Sri Saket in 1966 and received full ordination as a bhikkhu the following year, beginning a decade of training under Ajahn Chah at Wat Nong Pah Pong before the 1975 founding of Wat Pah Nanachat his first article opens with.
That the monk credited with carrying Thai forest monasticism into durable institutions across Britain and beyond had spent his twenties first as a wartime medic and then as a Peace Corps teacher on the other side of the world from any Buddhist training, marks Robert Jackman's pre-ordination decade as a documented case where the discipline Sumedho later brought to building monasteries abroad was already visible in the years he spent serving, and looking, before he ever took robes.
