The gift is from the Atlanta-based West Foundation's 19th-century collection. The collection includes 49 paintings and 41 sculptures.
The works include landscapes by Frederic Edwin Church and Jasper Crospey, portraits by Rembrandt Peale and William Sydney Mount and sculptures by Hiram Powers and Chauncey Bradley Ives. The new pieces go on view next week as part of the High's permanent collection.
High officials said the addition of the collection establishes the museum as a major resource for 19th-century American art. The museum has more than 12,000 works in its permanent collection.
