Rob Stuart, whose efforts to transform Philadelphia ranged from encouraging the use of Schuylkill River Park to bringing pedicabs here, died Wednesday.

Stuart was a regular presence in City Hall as he promoted his causes and issues, and on Thursday, Councilmen Curtis Jones Jr. and Darrell Clarke praised Stuart's contributions to the city.

"Rob Stuart did not believe an eco-friendly Philadelphia, nation or world was a fantasy but more of his planned vision," Jones said. He added that Stuart was the one who had invited him to study how drilling for natural gas could affect Philadelphia.

Stuart was the president and executive director of Evolve Strategies, which helps nonprofits use technology to promote their causes. He leaves behind his wife, Sarah Clark-Stuart, who also has been very active on city issues, and their two daughters.
