Re your article (The invisible women, G2, 17 October), as an ex-architect turned design and technology teacher (childcare issues), I contacted the publishers of our A-level textbook to explain that Ray Eames was not the brother of Charles but his wife. Of course, when the next edition was published the same misconception was repeated.

• Jo Steranka states: “Get rid of your dishwasher – it wastes energy and water” (Letters, 18 October). In fact, a dishwasher uses much less energy and water (as little as one-sixth, with modern machines) than washing by hand. The belief that anything that makes life easier must be worse for the environment is built on unfortunate moralistic foundations.

• With the greatest respect to Jo Steranka, why do we need to “hire a car to go on holiday”? Over the years my husband and I have been to Italy, Poland, France and numerous places in the UK, using trains and buses (and our legs).

• Suzan Delivuk (Letters, 18 October) suggests a visit to one’s GP to receive the flu jab. I made my appointment last week and turned up on Wednesday this week. Clean out of the vaccine. New appointment made for early November. What a shambles!

• While it was pleasing to see a review of Meic Povey’s Fel Anifail (17 October), it might have been helpful to advise readers that the play is in Welsh (if with simultaneous translation for non-Welsh speakers).
