Genius, Richard Trevithick's Steam Engines

Genius' is an over-used, but rarely-accurate, description applied to
remarkable figures. In the case of Richard Trevithick, however, its use is
not only apt, but could even be regarded as something of an understatement.

Philip Hosken's 'Genius' offers a perfect introduction to the great
engineer. Combining detailed and original research, the result is a clearly
stated, unbiased and readable account of his life and achievements.

From childhood and early motivation, through feverish experimentation and
frustration, to the eventual triumph of his revolutionary high pressure
cylindrical boiler, 1801 road engine and the world's first railway
locomotive, the author explains how and why Trevithick became a giant of
invention and innovation.

Laying to rest myths regurgitated by less-diligent writers, while not
neglecting the major contributions to the story of Papin, Newcomen, Savery
and others, Hosken employs the kind of scientific rigour which the
protagonist of his book might recognise and approve.

If you only read one book about Richard Trevithick, make sure it's this one.
