Ten innovative thinkers and doers will talk about issues such as poverty, sustainability and education at this year’s TEDxPittsburgh. Announced this week, this diverse group of educators, founders, physicians—there is even a comic—will take the stage at the event themed “Bridges: Ideas that Connect Us” from 10 a.m. to 5 p.m. on May 23 at the Byham Theater.

“We chose to focus on regional speakers—not fly in people—and highlight those who are doing work in the community,” says co-organizer Kacey Wherley.

Host for the day is Katie O’Malley, assistant communications manager in the Office of Mayor William Peduto. NEXTpittsburgh is media sponsor.

Chosen from over 100 applicants, the group was selected based on the unique nature of their talk, how it relates to Pittsburgh and ultimately how the topic relates to other parts of the world, says Chris Daley, co-organizer.

“If you have a good idea at one location in the world, it can be replicated to another,” he says.

The seven- to 18-minute presentations will be live-streamed and posted on the TED global website to be shared with the rest of the world.

“We encourage engagement and we’re hoping we have an idea presented that someone will tweet about or put a note in their own notebook about something they want to try for themselves,” says Daley.

TED, which stands for Technology, Education, Design, is a model that started in Long Beach, Calif. 25 years ago when an audience of open-minded influential individuals first gathered to hear presenters from various disciplines. TEDx gatherings have expanded to communities nationwide, sparking conversations at the local level. The “x” means that the event is independently organized.

Here in Pittsburgh, the TEDx talks grew from 100 attendees in 2013, when it was called TEDxGrandviewAve, to a sell-out audience of 500 last year. Attendance at this year’s event will be capped at 650, says Wherley.

“We chose to not quadruple the growth again and to focus on the content and help keep it intimate,” she adds.

“We know that a special responsibility comes with having the city’s name attached to our TEDx. Our goal is to represent the people, ideas and energy of Pittsburgh and to do it all justice,” says Daley.
