Death of a priest
The 1977 murder of Father Rutilio Grande sent shockwaves through El Salvador. The 48-year-old Jesuit priest was an outspoken champion of the poor in the deeply divided central American nation. In the immediate aftermath of his murder, the Archbishop of San Salvador, Oscar Romero, took the unprecedented step of holding just one single mass, ordering all other churches in his archdiocese to cancel theirs. Romero also refused to attend any government functions. Father Grande was one of the first priests to be killed by security forces in the years leading up to the bloody Salvadoran civil war. His murder marked a turning point as the church became increasingly involved in promoting social justice, and other priests became more outspoken against the government's repression of dissent. Mike Lanchin has been hearing from Gabina Dubon, who worked with Father Grande in his rural parish, and to theologian and author, SisterAna Maria Pineda.

The man who invented the scratch card
In May 1974, scratch cards went on sale for the first time in the US State of Massachusetts. Free giveaway and coupon games from stores had been commonplace across the USA during the 1950s and '60s – but players could easily cheat. The mathematician John Koza was hired to make the games more secure; he succeeded in making the modern-day scratch card. He tells Johnny I’Anson how he convinced the state-run lotteries to use his invention to offer cash prizes. Eye-witness accounts brought to life by archive.

GLP-1: A breakthrough for diabetes and obesity
In the 1980s, scientists made a discovery that would eventually lead to the development of drugs now used worldwide to treat diabetes and to help people manage obesity through weight loss injections.One of the key scientists behind this breakthrough was Svetlana Mojsov. She discovered that a hormone called GLP-1 (glucagon-like peptide-1) plays an important role in how our bodies respond to food. Svetlana’s work laid the foundation for a drug company to develop treatments based on GLP-1 — first for type 2 diabetes, and later for weight loss. She tells Gill Kearsley her story.Eye-witness accounts brought to life by archive. Witness History is for those fascinated by the past.

The UK’s first black-owned music studio
Sonny Roberts, a Jamaican carpenter, arrived in Britain in the 1950s. It was a time of racial disharmony, including the Notting Hill riots and the murder of Kelso Cochrane. In this tense atmosphere, black musicians struggled to make a name for themselves. Then in 1961, Roberts set up the UK’s first black-owned music studio, Planetone, in a basement in Kilburn. The studio gave the Caribbean community a musical platform. In later years, Roberts produced Nigerian band Nkengas’ album, Destruction - one of the earliest examples of Afrobeat in the UK. His 1987 production of Judy Boucher's Can't Be with You Tonight reached number two in the UK Singles Chart, beaten only by Madonna. Roberts laid the foundations for black British music. Ben Henderson speaks to his daughter, Cleon Roberts.This programme contains outdated and offensive language.Eye-witness accounts brought to life by archive.
