'Yes, this was the Rocker residence', he declared, with a distinct and entirely justifiable sense of pride. 'There used to be a portrait of Malatesta on that wall, and of Bakunin on that wall.'
Hang on a moment - entirely credible but how does he know? Well, because Rudolf Rocker's son, the artist Fermin Rocker, wrote a wonderful memoir of growing up in Dunstan Houses - graced by his own drawing of the building.
The family moved in in about 1910. 'Dunstan Houses', Fermin recalled, 'though hardly an abode for the affluent, nevertheless had its own class distinctions and offered a scale of accommodations for the poor, the poorer, and the poorest. ... No. 33 was in what might be termed the luxury wing of the building. We had such conveniences as a private kitchen and a private lavatory ...'
Rocker's own memoir, The London Years, has a drawing of him by his son on its cover.
