The Committee of Fifteen was a New York City citizens' group that lobbied for the elimination of prostitution and gambling. It was established in November 1900. The Committee hired investigators who visited city locations where prostitution and gambling was alleged to have taken place and filed reports on each site. The investigators visited bars, pool halls, dance halls, and tenements during the year 1901. The investigators posed as clients to determine the locations where prostitution took place.
The Committee disbanded in 1901 after evaluating the investigations and reporting to Governor Benjamin Barker Odell, Jr. It was succeeded by the Committee of Fourteen.
The Committee of Fifteen has sent to Gov. Odell a letter expressing approval of the legislation proposed by the Tenement House Commission in regard to the suppression of the social evil in tenement houses.
