[3] She traveled to Europe periodically between 1890 and 1895, painting alongside her father in England, Ireland and Scotland, and studying at Académie Julian in Paris.

Her active professional output slowed after the death of her young son, Herbert, in 1910, yet she continued to paint landscapes abroad, exhibit work and participate in artistic communities.

Throughout the 1910s she carried out commissions, including a World War I poster distributed nationally by the Red Cross, as well as a series of eight portraits of Columbia University professors.

Like many American artists at the turn of the 20th century, Brewster made paintings of scenes from her travels; the Huntsville Museum of Art has one of fishermen in Volendam.

The catalogue for the 2008 exhibition, edited by Judith Kafka Maxwell, contained extensive biographical articles, as well as the first scholarly appraisals of her life and works within the context of late Victorian and early twentieth century women artists.
