Hydraulic rotary oil well drilling Christmas tree oil well Spindletop oil field	Anthony Francis Lucas[15][16][17][18][19][20][21][22]	Working near Beaumont, Texas, Lucas struck oil on January 10, 1901, the largest gusher ever at that time. The discovery of oil at Spindletop led to widespread oil exploration and economic development in the state, later becoming known as the Texas oil boom.[23]
Sloan Great Wall	Mario Jurić (co-discoverer)
First self-propelled torpedo	Giovanni Luppis[24]	Luppis came upon the unfinished plans of an unknown Austrian Marine Artillery officer for a small self-propelled boat loaded with explosives that could be deployed against enemy ships and steered from land. Luppis developed a prototype but was unsatisfied, but approached British engineer Robert Whitehead with the idea.[25] Whitehead developed the concept into a successful self-steered explosive device which would strike below the waterline. Though the device was heavily modified from Luppis' concept and became known as the Whitehead torpedo, Whitehead credited Luppis as its inventor.[26]

Forensic fingerprinting	Juan Vucetich[54]	Created the first method of recording the fingerprints of individuals on file, associating these fingerprints to the anthropometric system of Alphonse Bertillon, who had created, in 1879, a system to identify individuals by anthropometric photographs and associated quantitative descriptions. In 1892, after studying Galton's pattern types, Vucetich set up the world's first fingerprint bureau.
