From now on, he lived in Vienna as a freelance artist and mainly took to landscape portrayal in the technics of coloured etching which he produced by means of two or three metal sheets.
At the academy, R. Lux had met (the later professor) Ferdinand Karl Gold, five years younger than Lux who became his lifetime friend. The London periodical for international arts “The Studio” published in the column “Studio Talk” a detailed report already in 1907, four pages in length, about the two young artists.
Here it is expressed what is later emphasized by many criticsthat R. Lux has developed a special mastery.They especially underline the ability of depicting fluent water, whether rivers or even the sea. The members of seafaring nations know about measuring the quality of a marine painter mainly in shaping the sea, the element water, and in the second place, in depicting the ship.
Lux succeeded in this special art in the small size of exlibris, a fact to which numerous bookplates for different collectors testify.
In the column of “The Studio” the illustration of a self portrait of the artist is found as a cold needle etching which turned out very well – as shown in the comparison with a photo from 1906.
R. Lux belongs to the “quiet ones in the country”,but needed this quietness to find himself, to their self – fulfillment !<br />His teacher, Prof. a. DELUG, once said: “Heads drawing from nature, every simple coachman can learn if you try to learn him ; but it is poetry a man has to feel!”, so that was a warning for all the others in the course, but not for R. Lux !He was the man who had this sensitivity to be able to express perception in his works !
A man of that disposition has got difficulties in the external materialistic world ! In February 1921 the painter got married to Karla Schlegelmilch who cared for him and who was able to keep away from him all troubles from outside.<br />Since 1921, the painter’s address is known in Wien VIII , Josefstädterstrasse 16 where he still was living in 1927. In the “Österreichischen Jahrbuch für Exlibris und Gebrauchsgraphik”from the year 1935 ( volume 30) you can find under the column “Neuerscheinungen” the address Wien III, Dietrichgasse 59 – 63, Stiege 22.
