Who among the following was not associated with Bloomsbury Group?

The correct option is Edmund Husserl.

The Bloomsbury Group was an influential group of associated English writers, intellectuals, philosophers, and artists in the first half of the twentieth century. Their work and outlook deeply influenced literature, aesthetics, criticism, and economics, and they famously lived and worked near Bloomsbury, London.

Let's look at the association of each individual listed in the options:
1. Virginia Woolf: A central figure of the Bloomsbury Group, she was a pioneering modernist writer and the sister of Vanessa Bell (another core member).
2. John Maynard Keynes: The famous economist who was a key member of the group, contributing to their intellectual debates and closely associated with the other members.
3. Lytton Strachey: A prominent biographer and writer, he was one of the founding members of the group.
4. Edmund Husserl: A renowned German philosopher who established the school of phenomenology. He worked in Germany and had no association with this British intellectual and artistic circle.

Therefore, Edmund Husserl is the correct answer as he was not associated with the Bloomsbury Group.
