Elizabeth Roboz Einstein
Roboz married Hans Albert Einstein, first son of physicist Albert Einstein, and professor of hydraulic engineering at the University of California, Berkeley, in June 1959. They did not have any children together, although Hans had four children from his first marriage to Frieda Knecht, only two of whom survived into adulthood. Hans died on July 26, 1973, and Roboz wrote a biography of him, "Hans Albert Einstein: Reminiscences of his Life and our Life Together" (1992).
Baby Einstein
The success of Baby Einstein was estimated to be nearly $400 million based on revenues. Julie was named "Entrepreneur of the Year" and won various awards, and one in three U.S. households with babies were found to own at least one Baby Einstein product. It received positive media and Aigner-Clark appeared on the "Oprah Winfrey Show", "Good Morning America", "The Today Show", and "USA Today", among others. President George W. Bush mentioned the Baby Einstein Company in his 2007 State of the Union address, which Aigner-Clark was invited to attend.
