Which BBC Radio 4 biography program devoted a 2013 episode to Ada Lovelace?

The BBC Radio 4 biography program that devoted a 2013 episode to Ada Lovelace was Great Lives.

The episode, first broadcast on 17 September 2013, featured television presenter Konnie Huq choosing Lovelace as her “Great Life.” Presenter Matthew Parris and social technologist Suw Charman-Anderson discussed Lovelace’s mathematics, her collaboration with Charles Babbage, and her reputation as an early computer-programming pioneer.

Great Lives is a long-running BBC Radio 4 discussion series in which a guest nominates a person who has inspired them. An expert joins the conversation, so the program is more focused on biography and interpretation than on a conventional chronological documentary.

A common mix-up is The Life Scientific, another BBC Radio 4 program that interviews scientists and researchers. In Our Time has also broadcast an Ada Lovelace episode, but it is a broader ideas-and-history discussion program rather than the 2013 biography episode described here.
