Symphony Hall, Springfield: Symphony Hall is a concert venue in Springfield, Massachusetts.  Constructed between 1911-1913 and originally known as "The Auditorium," Symphony Hall is known for its excellent acoustics and Greek Revival architecture.  It is part of the architecturally significant Springfield Municipal Group, and sits beside an ornate, 300 foot tall Italianate Campanile, which, in turn, is located next to Springfield's Greek Revival City Hall.  The Municipal Complex's architecture is a notable example of the City Beautiful style made popular by Daniel Burnham, an architect from Chicago, Illinois, in the early 20th century.  The Springfield Municipal Complex was dedicated by President William Howard Taft in December 1913.  In his dedication, Taft praised the three buildings as "one of the most distinctive civic centers in the nation, and indeed, the world."

Chilliwack Cultural Centre: The Chilliwack Cultural Centre is a performing arts venue located in downtown Chilliwack, one hour east of Vancouver, British Columbia.  The $22 million cultural facility celebrated its grand opening on September 25, 2010 with a concert by Lisa Howard, Jason Graae, David Burnham, Jessica Hendy, and Scott Coulter.

Rock Against Howard: Rock Against Howard, Musicians Against the Liberal Government is an Australian compilation CD featuring anti-Coalition musicians, released in 2004.  The project hoped to inspire young voters to turn out in federal elections that year to vote against then-Prime Minister John Howard, but Howard's party prevailed all the same.

Graham, Anderson, Probst &amp; White: Graham, Anderson, Probst & White (GAP&W) was a Chicago architectural firm that was founded in 1912 as Graham, Burnham & Co.  This firm was the successor to D. H. Burnham & Co. through Daniel Burnham's surviving partner, Ernest R. Graham, and Burnham's sons, Hubert Burnham and Daniel Burnham Jr.  In 1917, the Burnhams left to form their own practice, which eventually became Burnham Brothers, and Graham and the remaining members of Graham, Burnham & Co. – Graham, (William) Peirce Anderson, Edward Mathias Probst, and Howard Judson White – formed the resulting practice.  The firm also employed Victor Andre Matteson.

Frederick Russell Burnham: Frederick Russell Burnham DSO (May 11, 1861 – September 1, 1947) was an American scout and world-traveling adventurer.  He is known for his service to the British South Africa Company and to the British Army in colonial Africa, and for teaching woodcraft to Robert Baden-Powell in Rhodesia.  He helped inspire the founding of the international Scouting Movement.

Howard Mather Burnham: Lt. Howard Mather Burnham (March 17, 1842 – September 19, 1863), is best known for having fought and died at the Battle of Chickamauga in Georgia, during the American Civil War.

Big Brother Bluff: Big Brother Bluff ( ) is a high, angular granite bluff, 2,840 m high, along the west wall of Daniels Range, 6 nmi north of Mount Burnham, in the Usarp Mountains.  It was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1963–64, because it is visible from 50 nmi north and from many points across Rennick Glacier.  Hence the reminiscence from George Orwell's famous saying from "Nineteen Eighty-Four", "Big Brother is watching you".

John Hays Hammond: John Hays Hammond (31 March 1855 – 8 June 1936) was a mining engineer, diplomat, and philanthropist.  Known as the man with the Midas touch, he amassed a sizable fortune before the age of 40.  An early advocate of deep mining, Hammond was given complete charge of Cecil Rhodes' mines in South Africa and made each undertaking a financial success.  But after the dismal failure of the Jameson Raid, Hammond, along with the other leaders of the Johannesburg Reform Committee, was arrested and subsequently sentenced to death.  The Reform Committee leaders were released after paying large fines, but like many of the leaders, Hammond left Africa for good.  He returned to the United States, became a close friend of President William Howard Taft, and was appointed a special United States Ambassador.  At the same time, he continued to develop mines in Mexico and California and, in 1923, he made another fortune while drilling for oil with the Burnham Exploration Company.  His son, John Hays Hammond, Jr., patented over 400 inventions, and is widely regarded as the father of "radio control".

Howard Burnham: Mather Howard Burnham (May 27, 1870 – May 4, 1917), went by the name of Howard and his brother was the celebrated scout Frederick Russell Burnham.  He traveled the world, frequently worked as a mining engineer and, during World War I, he became an intelligence officer and spy for the government of France.  He had a wooden leg which he used to conceal tools for spying when he was behind enemy lines.

Mount Burnham (Oates Land): Mount Burnham is a projecting, bluff-type mountain, 2,810 m high, along the western wall of the Daniels Range, 6 mi south of Big Brother Bluff, in the Usarp Mountains.  It was mapped by the U.S. Geological Survey from surveys and from U.S. Navy air photos, 1960–63, and named by the Advisory Committee on Antarctic Names for James B. Burnham, ionospheric physicist who wintered at South Pole Station in 1958 and 1961.
