Ruth Mulan Chu Chao (Chinese: 趙朱木蘭; pinyin: Zhào Zhū Mùlán; March 19, 1930 – August 2, 2007) was the matriarch of a Chinese-American philanthropic family. In 2016, Harvard Business School dedicated the Ruth Mulan Chu Chao Center in her honor, making it the first building at the business school named for a woman and an Asian American. Four of Chao's six daughters attended the business school, including former United States Secretary of Labor and Secretary of Transportation, Elaine Chao.
