This year’s Deans Lecture will feature developmental economist and Nobel Peace Prize recipient Muhammad Yunus, the university announced last week. Tickets are free for the event, which will be held in Cohen Auditorium at 4:00 p.m. on April 20. Yunus is known for pioneering the use of microcredit — giving small loans to those not eligible for traditional loans — by founding Bangladesh’s Grameen Bank in 1976. He will cover this among other topics in his talk, titled “Social Business Can Address Pressing Social Problems.” To preview the event, the documentary “To Catch a Dollar: Muhammad Yunus Banks on America” will be screened in the Sophia Gordon Multipurpose Room at 7:30 p.m. on April 19. The screening will be followed by a question−and−answer period with Gayle Ferraro, the filmmaker.
