Fertiliser and poison gas: The legacy of chemist Fritz Haber
The Forum
May 4, 2022

German chemist Fritz Haber's discovery of how to turn atmospheric nitrogen into ammonia is seen as one of the most significant of 20th century science - it enabled the industrial manufacture of fertilisers, which now provide food for up to half the planet's people.

But he was also responsible for the development and deployment of poison gas on the battlefields of World War One and is remembered by some as the 'father of chemical warfare'. His was also a life touched by personal tragedy and a struggle against a Jewish heritage that at first threatened to hold back his career, and would later send him into exile.

Bridget Kendall examines a life that epitomises science’s capacity to create and to destroy.

The unfolding history of the magazine

When magazines first emerged, they were the preserve of an elite who could afford to pay for them. But as time went on, the cost of paper fell, printing technology became more streamlined, literacy improved and would-be publishers spotted an opportunity to connect with audiences hungry for information and entertainment.

Magazines found a place to appeal to all types of interest, in the same way that the internet does today. In their heyday they attracted some of the best writers such as Charles Dickens and Ernest Hemingway, sometimes acting as a vehicle to establish literary careers. Later magazines were to become the go-to place for quality photography and design.

Falling advertising revenues have largely contributed to the decline of printed magazines, as well as editions moving online. However some titles have found a way of reinventing themselves in the 21st century.
