"I thought it might be better to be like a chameleon — able to adapt and change and blend with our environment rather than conquer it."

Said Ross Langdon, a Tasmanian-born architect who built "eco-lodges and socially sustainable tourism in ecologically sensitive locations." He died in the Nairobi terror attack, along with his partner Elif Yavuz, a Harvard PhD and malaria specialist, who worked for the Clinton foundation.

"Elif was brilliant at her job and a joy to work with.... She was a friend both in and out of the office, and always had a great sense of humor – recently, her baby belly had been the subject of a number of jokes."
