威廉．凱斯 (William Keith) 是一位蘇格蘭裔的美籍畫家，以加州風景的作品而享譽於美國畫壇。父親早逝，1850年隨著母親與姊妹移民到美國紐約，凱斯當過木雕的學徒，回歐洲後幾經波折才定居在舊金山，也曾經跟友伴 Harrison Eastman 合夥幹過雕刻的業務。當初以水彩畫為創作的媒介，1868年他才邁入油畫的領域。
凱斯畫了不少加州優勝美地 (Yosemite) 和內華達山脈 (Sierra Nevada) 的景緻，這幅作品《Spring Landscape (Spring in Marin County)》則是舊金山北邊馬林郡的春天風景。凱斯的繪畫觀是：「創作的動機需來自於內在的感受與激發，不能全然源由於外在景物的引導。」
" My subjective pictures are the ones that come from the inside. I feel some emotion and I immediately paint a picture that expresses it. The sentiment is the only thing of real value in my pictures, and only a few people understand that. " (William Keith, from 1913 Exhibition booklet, Art Institute of Chicago.)
