Until I Have Crossed That River is the memoir of Dr. Bashir Ahmed, born in 1951 in the village of Kuttapara, Bangladesh, into a devout Muslim family where children herded cattle and learned the Quran before they learned arithmetic. The story begins with a single act of vision — his eldest brother's decision to enroll him in secular school — and follows the current that decision set in motion across seven decades and four continents. Bashir earned scholarship after scholarship, never borrowing a penny for his education, survived the Bangladesh Liberation War of 1971 and the devastating famine of 1974, lost his father in a sudden roadside accident, and still completed his degrees at the University of Dhaka before winning a Colombo Plan scholarship to the Australian National University and eventually a PhD at the University of California, Berkeley. He built a career at the U.S. Census Bureau spanning three decades, raised three sons who became doctors, survived a quadruple bypass, performed Umrah in Mecca, and in retirement returned to Bangladesh to fund a classroom at Dhaka University, restore a childhood madrasa, and endow a graduate fellowship at Berkeley. Written with quiet dignity and profound gratitude, this is the story of a man who understood that crossing a river is not the destination — it is learning to help others cross.
