Bob was born in 1918, the first son of George and Anna Rastovich. He was mechanically inclined and many of his inventions are still on the farm today. He installed a windmill to the top of the barn, connected to the radio so that when the wind blew, the radio would play.
In June 1941, he joined the U.S. Army as part of the Selective Training and Service Act of 1940, requiring all men 21-45 to register for the draft. He spent three years as a lineman in Alaska, working on the power lines before getting a furlough home in 1944. In 1944, he fought in Western Europe, returning home in October 1945.
After his return home, he worked for Shevlin-Hixon as a mechanic. On May 19, 1947, Bob was underneath a truck when it slid off the jack. The loss of Bob was a blow to the family. Everyone said that Anna was never the same again. Mike, Martha, and Danny each named one of their children after Bob. Danny continued tinkering with machinery on the farm, creating his own inventions as Bob used to.
