Scott Selig, the young and charismatic development executive with prominent Atlanta real estate company Selig Enterprises Inc., has died. Selig, who was battling cancer, was known for his defiance of the disease, which inspired an active social media following over the past year under the Facebook campaign #ScottStrong. It grew to several thousand supporters, including friends and real estate colleagues. Selig had convinced his father Steve Selig to form the division and make a stronger push into development. Until that point, Selig Enterprises had been known more as an investor. Selig was 47 years old. Despite his illness, he pressed on with more endeavors over the past year. As president of Selig Development, a new division at Selig Enterprises, he led the 100 year-old company’s expansion to mixed-use projects including the $400 million 1105 West Peachtree and a $1 billion development along Chattahoochee Ave.
