Blockarchitecture

Curation or selection offers up probably the greatest challenge for the contemporary architect. With the onslaught of information, the emphasis is now on what an architect chooses to respond to rather than what is available to him or her in terms of sources. Iain Borden discusses how Block Architecture's responsive position enables the firm to react with immediacy to its urban surroundings, while also resulting in highly attuned ‘architectures of suggestion and momentary thinking’.

Obituary: Erasmus (Bob) Hoch (1914–2008).

Obituary [Erasmus (Bob) Hoch; 1914–2008]. Erasmus “Bob” Hoch was born in New York City on August 1, 1914. He died in Brunswick, Maine, on April 6, 2008. Following military service in World War II, Bob enrolled at Columbia University, where he completed a doctorate in clinical psychology in 1950. He then served in the Veterans Administration (VA), rising to the position of chief clinical psychologist at the VA in Togus, Maine. In 1956 he joined the American Psychological Association (APA) as administrative officer in charge of state and professional affairs and wrote a monthly column for the American Psychologist titled “Psychology in the States.” Upon his death, humanity lost a fine human being, psychology lost an important contributor, and I mourn the loss of a good friend.
