From the link mentioned in another comment as a more stable and permanent URL: ""Math Blaster" is a 1983 educational game programmed by Richard Eckert and Janice Davidson, Ph.D. and distributed by Davidson & Associates." Wow. The timing of this post was opportune, because just yesterday I had a chance to see (again) Bob Davidson, the husband of Janice (Jan) Davidson and a leader of Davidson & Associates, at a meet-up of alumni of various Davidson Institute for Talent Development[1] programs for young people. The Math Blaster software was an early example of successful edutainment software, and it led to quite a bit of revenue that funded other software titles developed in-house or acquired over the years by Davidson & Associates. Jan and Bob Davidson timed the Dot Com boom perfectly in choosing a time to leave active management of Davidson & Associates and begin funding philanthropy, which for them has been most devoted to developing programs for unusually bright young people in the United States. The best-known program of the Davidson Institute is the Davidson Fellows program,[2] which gets in the news at least once a year as new Davidson Fellowship awards are announced,[3] but the biggest program by number of young people involved is the Davidson Young Scholars program,[4] which includes several alumni and I think some current members who are active participants here on Hacker News. We talk here on Hacker News about some other software entrepreneurs who get in the news a lot these days for their philanthropic efforts, but I thought I should give a shout-out to one of the early adopters of a career change to full-time philanthropy funded by a software fortune, the Davidsons, because their philanthropy has a direct influence on the Hacker News community.
