Spengler was born in Schaffhausen, Switzerland, the son of master builder Johann Conrad Spengler (1676–1748) and Maria Peter (c. 1683–1723).

He arrived at Copenhagen in 1743 and became a tutor to Christian VI of Denmark and later Frederick V of Denmark in the art of turning. From 1771 he was head of the Royal Art Chamber (Det Kongelige Kunstkammer), a position he held until his death in 1807. Among his works is "Beskrivelse og Oplysning over den hindindtil lidet udarbeidede Sloegt af mangeskallede Konchylier som Linnaeus har kaldet Lepas med tilfoiede nye og ubeskrevne Arter ", a treatise on shelled molluscs including many new species descriptions, of which six taxa are still valid. Spengler maintained a personal natural history collection, the Museo Spengleriano. Spengler is commemorated in the scientific name of a species of Southeast Asian turtle, Geoemyda spengleri. He is also celebrated in the common name of the Spengler's freshwater mussel, Margaritifera auricularia.
