Technology advances more rapidly than many of us can keep up with. Whether it’s in computing, the internet, mobile communications, blockchain, or biotechnology, potentially world-changing innovation is always under development.

It makes sense that youth would often be associated with ground-breaking inventions and discoveries. Often it takes fresh eyes and a new perspective to envision what the future might look like.

But the leading edge of technological innovation isn’t always pushed forward by the young. The first installment of The Business of Business “50 over 50” list highlighted trailblazers in the e-commerce field. Now, in our second installment, we are featuring 10 professionals who achieved great things or broke boundaries in technology and software fields after they reached age 50.

Here is who they are and how they impacted our lives.
