Laueite is a hydrous iron manganese phosphate. Strunz (1954) [paywall] named the mineral after Max von Laue (1879-1960), a pioneer in X-ray crystallography.
Laueite forms crystals to 1 mm alongside much larger leucophosphite crystals with green-brown mitridatite providing contrast. A good example for the locality. Dakota Matrix, Grenier collection, and John F. Barlow collection labels accompany this specimen. Please note the backside of this specimen (its altered triphylite matrix) has a saw cut. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
