Philosophically, Dubois may have had no problem with a great African American institution. On the other hand, he always believed ultimately in the co-mingling of groups and the interplay of talents and in the collaboration of groups.

Harlem was a development, a developer's dream and a place where residents had more space and more amenities than ever before. The subway reached 145th street about 1904, and it seemed that Harlem's destiny was to become largely a preserve of successful ethnics relocating and arriving. Then, overnight, the bust took place.

1900 was a bit of mixed bag, it seems to me, on the one hand, because this is the year when this country becomes the premiere producer of manufactured goods. Clearly, a lot of people were making a lot of money, but it's also a time that reflects the savaging of one of the deepest depressions.

Ironically, it is only when disaster strikes that the shuttle makes the headlines. Its routine flights attracted less media interest than unmanned probes to the planets or the images from the Hubble Telescope. The fate of Columbia (like that of Challenger in 1986) reminded us that space is still a hazardous environment.

The '50s in general are written off as a boring decade following the turmoil of the Second World War and its immediate aftermath - the postwar Labour government, the cold war, the arrival of the New Look in fashion, etc. But I remember it as a very exciting time - a pioneering, rule-breaking time, especially for the young.
