I haven’t known many geniuses in my life. Some brilliantly smart people, but only a tiny handful would I class as geniuses. I would class Douglas, because he saw things differently, and he was capable of communicating the way he saw things, and once he explained things the way he saw them, it was almost impossible to see them the way you used to see them

It changed my whole life. It's literally out of this world

- <b>Tom Baker</b>,

Hitchhiker’s is packed with that unique energy, all barmy and bristling and bold. This book can be witty, iconoclastic, godless, savage, sweet, surreal, but above all, it dares to be silly. Fiercely, beautifully silly

- <b>Russell T. Davies, writer and producer of <i>Doctor Who</i></b>,

He had almost a Wodehousian style and some of his phrases and jokes entered our language. He changed the way people spoke

- <b>Stephen Fry</b>,

There has never been another writer remotely like Douglas Adams. He discovered a completely new genre – scientific wit – and having discovered it he raised it to dizzying heights

- <b>Tony Robinson</b>,

Quite good I suppose, if you like brilliantly entertaining books written with a touch of imaginative genius

- <b>Griff Rhys Jones</b>,

Very occasionally a book comes along that changes the way you laugh and what you laugh about

- <b>Richard Dawkins</b>,

One of the world’s sanest, smartest, kindest, funniest voices
