artist
Greenwood's early days were spent working in a mill, training as an artist only when time and money permitted until his employer, and owner of the mill, noted the young worker's innate artistic talent and financed his education at Wilbraham Academy. After studying oil painting for two semesters, he returned to Worcester, supporting himself teaching painting to young pupils. Greenwood's talent was recognized nationally when he was chosen as the only artist from the area to exhibit at the World's Columbian Exposition of 1893. In 1905 the Worcester Art Museum mounted a one-man show of his paintings, choosing to highlight their local renowned artist instead of works by other landscape painters like Boudin, Corot, Enneking, and Inness.
