In 1977, when he was 22 years old, inventor Alex Lidow had the sort of eureka moment most techies would kill for. While in graduate school at Stanford, Lidow co-invented, along with Thomas Herman, a type of device called the HEXFET power MOSFET that would make his family’s old company, International Rectifier, more than $930 million in royalties. And it turned Lidow's grandfather, a Lithuanian Holocaust survivor, and his father, who fled Berlin in 1937, into important players in the hardware industry.
