Born in Newcastle, where he spent most of his life, Alder was the owner of a cheese shop before becoming a zoologist and malacologist, specializing in the Tunicata and gastropods. He became interested in natural history later in his life when he met a group of local naturalists and became an early member of the Literary and Philosophical Society, of Newcastle, alongside Joseph Swan and Robert Stephenson, in 1815. After first studying geology and botany, Alder focused on British molluscs, land and freshwater snails, authoring many papers on them. In 1829, he became, along with Albany Hancock, a founding member of the Natural History Society of Northumberland. For this book on sea slugs and molluscs, he travelled all over Britain collecting specimens. He published it in parts between 1844 and 1855, in collaboration with Hancock, and subsequently gained international recognition for his work.
