• Anton Wallich-Clifford, co-founder of the Simon Community, was 55 when he died in 1978, not 58 as an article said (He changed the way we view the homeless. Time for a blue plaque?, 30 July, p18).
• The neuroscientist Kári Stefánsson should have been referred to on second and subsequent mentions as Kári (‘We have hope for breakthroughs’, 30 July, New Review, p24). This accords with convention in Iceland, where surnames are typically patronymic, indicating the person is the son or daughter of the father, rather than being a family name.
