Henry Twiselton Elliston (c. 1801 – 1864), was an English musical composer and inventor.
Having decided on adopting music as his profession, he received a careful training, and became a sound theoretical musician, and an able performer on the organ and several other instruments.
On his father presenting an organ to the parish church of Leamington, Elliston was elected organist, and held the post till his death.
In the subsequent enlargement of the organ he exhibited considerable mechanical ingenuity, and invented a transposing piano on a new and simple plan.
Elliston himself built the music hall in Bath Street, with his brother William, who emigrated to Australia, he established the County Library.
