Did Alfred Nobel wrote a book?

Alfred Nobel did not write a book in the traditional sense. He was primarily known for his inventions, particularly dynamite, and for establishing the Nobel Prizes.

However, he did write a significant amount of scientific and technical papers as well as poems and essays on various topics. Some of his writings were published during his lifetime, but much of his work was only discovered and published after his death.

So, while he didn't author a complete book in the usual meaning, he did leave behind a considerable body of writings.
