The development of the steam engine was a decisive factor in the first industrial revolution in Britain. It allowed energy stored in steam to be converted into mechanical work. Several key inventions and innovators contributed to the development of the steam engine over centuries, culminating in James Watt's improved steam engine in 1763 which truly developed the steam engine with a separate condenser.

bodies and discovered maxillary sinus, the
moderator band of the heart and ventricles of the
brain, making precise anatomical drawings.

observation and dissection overthrowing many of
Galen’s misconceptions and became the foundation
of Modern Anatomy.
