His paternal grandfather, Samuel P. Bush, worked as an executive for a railroad parts company in Columbus, Ohio, and his maternal grandfather, George Herbert Walker, led Wall Street investment bank W. A. Harriman & Co. Bush was named after his maternal grandfather, who was known as 'Pop', and young Bush was called 'Poppy' as a tribute to his namesake. The Bush family moved to Greenwich, Connecticut in 1925, and Prescott took a position with W. A. Harriman & Co. (which later merged into Brown Brothers Harriman & Co.) the following year. George H. W. Bush died on November 30, 2018, aged 94 years, 171 days, at his home in Houston.
