Ellen S. Miller

Campaign finance disclosure in the United States existed on paper long before most people could use it. Miller founded the Center for Responsive Politics in 1983, which turned Federal Election Commission filings into the searchable OpenSecrets database of who gives to whom, now a standard tool for reporters and voters checking a candidate's backers. In 2006 she co-founded the Sunlight Foundation, which pushed Congress and agencies to publish data online in machine-readable form and funded the tools to read it. Sunlight wound down in 2020; OpenSecrets continues.
