Brotan, who was Chief Engineer of the main workshops of the Royal Austrian State Railways at Gmund, found that locomotive inner fireboxes of the usual type were both expensive, because the copper from which they were made had to be imported, and short-lived, because of corrosion resulting from the use of coal with high sulphur content. He designed a firebox of which the side and rear walls comprised rows of vertical watertubes, expanded at their lower ends into a tubular foundation ring and at the top into a longitudinal water/steam drum. This projected forward above the boiler barrel (which was of the usual firetube type, though of small diameter), to which it was connected. Copper plates were eliminated, as were firebox stays.

The first boiler to incorporate a Brotan firebox was built at Gmund under the inventor's supervision and replaced the earlier boiler of a 0−6−0 in 1901. The increased radiantly heated surface was found to produce a boiler with very good steaming qualities, while the working pressure too could be increased, with consequent fuel economies. Further locomotives in Austria and, experimentally, elsewhere were equipped with Brotan boilers.

Disadvantages of the boiler were the necessity of keeping the tubes clear of scale, and a degree of structural weakness. The Swiss engineer E. Deffner improved the latter aspect by eliminating the forward extension of the water/steam drum, replacing it with a large-diameter boiler barrel with the rear section of tapered wagon-top type so that the front of the water/steam drum could be joined directly to the rear tubeplate. The first locomotives to be fitted with this Brotan-Deffner boiler were two 4−6−0s for the Swiss Federal Railways in 1908 and showed very favourable results. However, steam locomotive development ceased in Switzerland a few years later in favour of electrification, but boilers of the Brotan-Deffner type and further developments of it were used in many other European countries, notably Hungary, where more than 1,000 were built. They were also used experimentally in the USA: for instance, Samuel Vauclain, as President of Baldwin Locomotive Works, sent his senior design engineer to study Hungarian experience and then had a high-powered 4−8−0 built with a watertube firebox. On stationary test this produced the very high figure of 4,515 ihp (3,370 kW), but further development work was frustrated by the trade depression commencing in 1929. In France, Gaston du Bousquet had obtained good results from experimental installations of Brotan-Deffner-type boilers, and incorporated one into one of his high-powered 4−6−4s of 1910. Experiments were terminated suddenly by his death, followed by the First World War, but thirty-five years later André Chapelon proposed using a watertube firebox to obtain the high pressure needed for a triple-expansion, high-powered, steam locomotive, development of which was overtaken by electrification.

A former Second Lieutenant of the Austrian navy (hence his later nickname "Captain") and graduate of the Polytechnic Institute of Graz, Lucas decided to stay in Michigan when he visited his relatives in 1879. He changed his original name, Lucie, into the form his uncle had adopted and became a naturalized American citizen at the age of 30. He worked in the lumber industry for some years and then became a consulting mechanical and mining engineer in Washington, DC. He began working for a salt-mining company in Louisiana in 1893 and became interested in the geology of the Mexican Gulf region, with a view to prospecting for petroleum. In the course of this work he came to the conclusion that the hills in this elevated area, being geological structures distinct from the surrounding deposits, were natural reservoirs of petroleum. To prove his unusual theory he subsequently chose Spindle Top, near Beaumont, Texas, where in 1899 he began to bore a first oil-well. A second drill-hole, started in October 1900, was put through clay and quicksand. After many difficulties, a layer of rock containing marine shells was reached. When the "gusher" came out on 10 January 1901, it not only opened up a new era in the oil and gas business, but it also led to the future exploration of the terrestrial crust.

Lucas's boring was a breakthrough for the rotary drilling system, which was still in its early days although its principles had been established by the English engineer Robert Beart in his patent of 1884. It proved to have advantages over the pile-driving of pipes. A pipe with a simple cutter at the lower end was driven with a constantly revolving motion, grinding down on the bottom of the well, thus gouging and chipping its way downward. To deal with the quicksand he adopted the use of large and heavy casings successively telescoped one into the other. According to Fauvelle's method, water was forced through the pipe by means of a pump, so the well was kept full of circulating liquid during drilling, flushing up the mud. When the salt-rock was reached, a diamond drill was used to test the depth and the character of the deposit.

When the well blew out and flowed freely he developed a preventer in order to save the oil and, even more importantly at the time, to shut the well and to control the oil flow. This assembly, patented in 1903, consisted of a combined system of pipes, valves and casings diverting the stream into a horizontal direction.

Lucas's fame spread around the world, but as he had to relinquish the larger part of his interest to the oil company supporting the exploration, his financial reward was poor. One year after his success at Spindle Top he started oil exploration in Mexico, where he stayed until 1905, when he resumed his consulting practice in Washington, DC.
