Borzou Daragahi compiles a superb report on Neda Agha-Soltan:

The second of three children, she studied Islamic philosophy at a branch of Tehran's Azad University until deciding to pursue a career in tourism. She took private classes to become a tour  guide, including Turkish-language courses, friends said, hoping to someday lead groups of Iranians on trips abroad. 

Travel was her passion, and with her friends she saved up enough money for package tours to Dubai, Turkey and Thailand. Two months ago, on a trip to Turkey, she relaxed along the beaches of Antalya, on the Mediterranean coast. She also loved music, especially Persian pop, and was taking piano lessons, according to Panahi and other friends. She was also an accomplished singer, they said.

But she was never an activist, they added, and she began attending the mass protests only because she was outraged by the election results.

More details of her life, and death, here.
