Laflin & Rand (established in 1872) introduced “Infallible” Dense Smokeless powder in 1900, then DuPont purchased Laflin & Rand in 1902.
In 1912 under the Sherman Antitrust Act, Laflin & Rand was dissolved and DuPont was split into DuPont Powder Co. (which retained DuPont Bulk, Ballistite, Empire and “Schultze” and was later DuPont American Industries), Hercules Powder Co. (formed by DuPont and L&R in 1882 and then dissolved in 1904; which retained “Infallible” and “E.C.”) and Atlas Powder Co.
Hercules sold the powder product line to Alliant in 1995.
