Bob Zumwalt was born in Hallettsville, Texas and grew up in that small South Central Texas town. He earned degrees in chemical engineering from Texas A&M (B.S.) and the University of Delaware (Ph.D.). Bob worked two years as a process design engineer for a large chemical company, served two years as a lieutenant in the US Army, and spent the remainder of his professional career as a specialist and consultant in mathematical modeling and process control for a large international oil company. His career - rich with interesting experiences, travel, and people - inspired many of his stories. In his spare time Bob enjoys listening to music, reading, writing, tennis, running and walking, and caring for rescued kitty cats. He and his wife Doris live in the old family home in Hallettsville - built by his grandfather in 1893. The couple have two grown-up sons.
