On the death of John Frederic Daniell he succeeded to the Chair of Chemistry at King's. Although primarily a chemist, the scientific contributions for which Miller is mainly remembered today are in spectroscopy and astrochemistry, new fields in his time.
Miller wrote the textbookElements of Chemistry, Theoretical and Practical, Part I Chemical Physics in 1855.[2] In the preface he acknowledged the assistance of Charles Tomlinson.
In 1870 Miller had completed the manuscript for Introduction to the Study of Inorganic Chemistry when he fell ill. He passed it to Charles Tomlinson to prepare it for publication.[5]
According to his obituary,[6] Miller married Eliza Forrest of Birmingham in 1842. He died in 1870, a year after his wife, and they are both buried at West Norwood Cemetery. They were survived by a son and two daughters.
