Transitions: Ray Tomlinson (1941-2016), a computer scientist who is credited with the invention of perhaps the world’s most personalized channel of digital communications–email–died last week at the age of 74. Tomlinson was working for Ratheon and developed email as a means to communicate on the ARPANET, the forerunner of the internet. By all accounts, he was a surprisingly laid-back and humble person. All he did was change, forever, the way people and companies communicate. His contribution to the digital age is immense and legendary. Thank you, Ray. Very well done.
