Dear Mr Musk,
It is a great pleasure to inform you that the IEEE Board of Directors selected you to receive the 2015 IEEE Honorary Membership, which is given for meritorious service to humanity in the IEEE's designated fields of interest and who are not members of the IEEE.
The award comes with the following citation:
“For leadership in and innovative contributions to space-exploration technology, combatting global warming and promoting science education, pediatric health, and clean energy.”
For nearly a century, the IEEE Awards Program has paid tribute to educators, researchers, inventors, innovators, engineers, and scientists whose exceptional achievements and outstanding contributions have made a lasting impact on technology, society, and the engineering profession. Each year the IEEE Awards Board recommends a small number of outstanding individuals for IEEE's most prestigious honors. You now join this select group.
Your award will be presented at the IEEE Honors Ceremony on Saturday, 20 June 2015 at the Waldorf Astoria, New York, NY, USA. Additional details regarding the award presentation will be sent separately via electronic mail by the IEEE Awards Staff.
Congratulations on your achievement, and thank you for your commitment to IEEE and its mission of advancing technology to benefit humanity.
Sincerely,
J. Roberto de Marca IEEE President
