Here is my list (the names are in no particular order - I can't imagine choosing the number one artistic influence!):
1) Rebecca Purdum - contemporary artist who I've been following since the 80s - ethereal abstraction (shows at Tilton Gallery, NYC)
2) Sam Scott - my professor at University of Arizona, initiated me into the true painter's life and practice; lyrical abstractions of nature
3) 12th Century Chinese Southern Song painters - poetry of nature and the seasons, veiling and unveiling of forms, contemplative technique
4) Georgia O'Keeffe - paint handling, morphology of forms (the major influence upon my early work)
5) Agnes Martin - repetition, natural order, poetry of painting, the grid
6) Mondrian - composition, subtle balances and rhythms within geometric structures
7) Jackson Pollock - the spontaneous gesture; the importance of psychology and the unconscious
8) Rothko - the luminosity of color
9) Bonnard - light and color, paint handling
10) Turner - abstraction of landscape, use of thick and thin paint, use of light and dark
11) Kandinsky - for the spiritual in art
12) Cezanne - the importance of the underlying structure of a painting
13) Monet - the way he perceived light and color, the broken brushstroke
14) Donald Judd - clean lines, no-nonsense Beauty, repetition, transcending the grid
15) Joan Mitchell - abstraction of nature, luscious use of paint, use of the white ground, importance of the single brushstroke
