early works of art
Martin Johnson Heade was an American painter known for his salt marsh landscapes, seascapes, and depictions of tropical birds (such as hummingbirds), as well as lotus blossoms and other still lifes. His painting style and subject matter, while derived from the romanticism of the time, are regarded by art historians as a significant departure from those of his peers.
Agnes Martin was an American abstract painter. Her work has been defined as an "essay in discretion on inward-ness and silence". Although she is often considered or referred to as a minimalist, Martin considered herself an abstract expressionist and was one of the leading practitioners of Abstract Expressionism in the 20th century. She was awarded a National Medal of Arts from the National Endowment for the Arts in 1998. She was elected to the Royal Canadian Academy of Arts in 2004.
