"The aim is to create awareness of museums, so that, when they are under threat, there will be public outrage. They mustn't be taken for granted. At the moment we're doing this through Museums Week, which is now becoming an institution - as someone once told me, in Britain if you do something once it's a novelty, if you do it twice it's an institution."
Although the Campaign for Museums has no budget of its own, it is strongly supported by a variety of associations. "It's entirely voluntary," says Grossman, "an SAS-type operation. We just want to go in and hit where we're needed with the minimum of grandeur or bureaucracy."
Lobbying people and begging for money take up around half his working hours at present. Why does he do it? The answer lies in Grossman's Massachusetts childhood. "I was very lucky to grow up near a couple of wonderful museums: the Peabody at Salem, which is one of the greatest maritime museums, and the Museum of Fine Arts in Boston, which is just the most wonderful museum in the world. Fortunately, my father did a lot of business with the Museum of Fine Arts, so as a child I usually went to a museum once a week. It was just as everyday a part of my life as going out to play baseball or going to the beach. But it was always thrilling. Even now, when I go back to the Peabody Museum, I still get the same thrill and I still remember what it felt like as a very, very small child. The Peabody has a great collection of ship models, plus Hawaiian chiefs' capes and spears from the South Seas, all of which was enthralling. I was very lucky to have such an outstanding museum right on the doorstep."

Not even open yet, the embryo Museum of Soho is staging children's walks on the two Saturdays of Museums Week. Parents can come, too, say the organisers, "providing they promise not to dampen the atmosphere". There will be two types of walks to cater for both children who already know the area and those who don't (booking: 0171-439 4303). "We'll take a sensible line on the brothels and strip clubs," says a spokeswoman. "Local children are immune to them anyway." Fund-raising is now gearing up towards the museum's hoped-for opening in five years' time, when it will house displays showing the social history of Soho over 400 years.
Who needs Hawaiian chiefs' capes when, on Thursday 23 May, you can attend workshops on how to produce your own hand-made bricks at Louth Museum (4 Broadbank, Louth, Lincolnshire LN11, 01507 601211)? "Anyone prepared to roll up their sleeves and put on a plastic pinny is welcome between 2 and 4pm," says curator Jean Howard.
