Born the son of Peter Augustus Macirone, an Italian merchant and former school teacher living in England, Maceroni became a Colonel of Cavalry and served as aide de camp to Joachim Murat, the King of Naples during the Napoleonic Wars (later writing his biography) and fought with the Spanish insurgents in 1822-1823 during the Trienio Liberal.
Francis opted to resume the original spelling, but is sometimes listed with the variant spelling. While serving as an aide to Murat, Maceroni introduced the Neapolitan Court to archery, cricket, and the concept of weekly dining parties. Unfortunately, cricket did not survive his departure.
In 1825 while living in Manchester, he became interested in the work of Sir Goldsworthy Gurney and attached himself to Gurney"s Regent"s Park workshop on the recommendation of Sir Anthony Carlisle, ostensibly to work on his own inventions.
He stayed six months and became involved enough in Gurney"s work - he witnessed one of the early carriage contracts - that he persuaded several friends to invest in the enterprise. After a time in Constantinople helping the Turks fight the Russians, he returned to London in 1831 and joined forces with Gurney"s former employee, carpenter John Squire.
In 1833, the two had constructed their own steam carriage. lieutenant was a straightforward vehicle that carried up to fourteen passengers, developed 30 horsepower (22 kW) at 14 mph (23 km/h) and ascended hills with ease.
The carriage ran for hire for some weeks between Paddington and Edgware with no serious mechanical problems and in 1834, after a new toll relief bill was passed by the House of Commons, Maceroni built a new and larger carriage.
But the bill failed in the House of Lords and Maceroni fell into financial difficulties. To meet the terms of the Belgian and French patents he had negotiated earlier, he shipped his two remaining carriages to Brussels and Paris in the care of the Italian speculator Colonel d"Asda. Doctorate"Asda drove the carriages around to great publicity for several months then sold them and disappeared with the money.
In 1835, Maceroni published a book on road steam power and tried to raise new capital, but a railway investment panic in 1837 doomed his chances and in 1841 the disclosure of serious mismanagement ended with the seizure of all his assets.
Maceroni lived in England for much of his life, and published his memoirs in 1838.
