Eunice Hunton Carter, a granddaughter of slaves, went on to become the lawyer who built the case against Charles “Lucky” Luciano, one the 20th century’s most powerful criminal kingpins. It was an assignment fraught with danger, but one Carter performed with tenacity, intelligence and a sense of mission, discovering the Achilles heel of a man who’d evaded prosecution for years.

Gabriella Gómez-Mont is neither an urban planner nor an engineer nor a politician. She’s an artist. But as creative director of Mexico City’s Laboratorio para la Ciudad (Laboratory for the City), she has tackled some of the thorniest problems confronting the modern metropolis—with astonishing success. She and her team launched one of the biggest open data projects ever seen, drawing numbers from institutions and individuals, building map upon map of their city, to better understand challenges as varied as traffic deaths and social isolation.

Today, cities as far flung as Seoul and Manila seek Gómez-Mont’s expertise. As host Sarmishta Subramanian puts it: “Her power of one is in a sense the power of millions—a faith in the talents and wisdom and energy of ordinary citizens, in ordinary neighbourhoods. A belief that change can be made thoughtfully, and for the better.”

Kathi Lynn Austin has targeted, investigated and helped to bring down some of the world’s most dangerous arms dealers, exposing transactions that fuelled the Rwandan genocide and shutting down smuggling networks that helped power years of civil war in the Congo. But she is neither a cop nor a CIA agent nor a crusading prosecutor. She’s merely an American civilian with a deep sense of moral outrage and a deeper reservoir of courage.

It’s been a decade since Sergei Magnitsky was tortured and killed in a Moscow prison. In that time, his name has become synonymous with rule-of-law and international justice—even as those principles come under attack around the world. It is memorialized in the laws of six countries allowing for sanctions against human rights offenders.

On this 75th anniversary year of D-day, the world marked the invasion that started the liberation of France from Nazi rule. Forgotten in the celebrations was a lynchpin of that operation, a man operating very far from the front.
