Henry Dircks FRSE FCS (26 August 1806 – 17 September 1873) was an English engineer who is considered to have been the main designer of the projection technique known as Pepper's ghost in 1858. It is named after John Henry Pepper who implemented a working version of the device in 1862. Dircks also investigated attempts at the invention of a perpetual motion device, writing that those who sought to create such a thing were "half-learned" or "totally ignorant". Dircks was born in Liverpool on 26 August 1806.

He was apprenticed to a mercantile firm and spent much of his free time studying practical mechanics, chemistry, and literature. Around the mid-1820s he began lecturing about chemistry and electricity while writing literary articles in the local press and scientific papers in the Mechanics' Magazine and other journals. In 1837 he became a life member of the British Association, and afterwards contributed papers to its proceedings. Two years later he wrote a pamphlet regarding a proposed union of mechanics' and literary institutions. He also wrote a short treatise entitled "Popular Education, a series of Papers on the Nature, Objects, and Advantages of Mechanics' Institutions", first printed in Liverpool in 1840.

He became a practical engineer, conducting railway, canal, and mining works, before progressing to the role of consulting engineer. He continued to investigate technologies and invent new devices, taking out several patents between 1840 and 1857. Dircks joined the Royal Society of Literature, the Royal Society of Edinburgh, and other scientific bodies. In 1867 he was elected a full Fellow of the Royal Society of Edinburgh, his proposer being William John McQuorn Rankine. In 1868 he was given an honorary degree (LL.D.) from Tusculum College in Tennessee. Dircks died in Brighton on 17 September 1873. (Wikipedia)
