In addition to her own artistic accomplishments, she endowed the Twining-Humber Award for Lifetime Achievement through Seattle’s Artist Trust. The award gives an annual $10,000. prize to a Washington State female artist over the age of 60 who has dedicated a substantial portion of her life to art. She understood the challenges most women artists face in pursuing their art in balance with family and societal expectations and she wanted to see those achievements acknowledged and celebrated.
