德国著名画家雷欧·阿森马赫(1904-1981)出生于亚堔，却成名于杜塞尔多夫。在这个首府城市，阿森马赫不仅在绘画方面拥有盛名，并且他对“Malkasten”艺术家协会自1924年入会以来的投入和支持也获得了艺术届的高度评价。

阿森马赫自幼跟随父亲赫曼·约瑟夫·阿森马赫学习壁画，之后进入亚琛应用艺术学院和技术大学学习，并曾跟随欧根·科林肯伯格学习绘画。20岁时他离开出生地前往杜塞尔多夫艺术学院，师从多宁格、斯帕兹、内泽尔、兰格等教授，后期则成为阿道夫·明泽尔教授的硕士研究生。就学期间阿森马赫即已经收到大量的订单，波恩彼得大教堂里精彩的壁画也是他的作品。

阿森马赫的绘画题材非常广泛，包括他旅途中的风景、人物肖像、静物写生以及裸体。他甚至被认为是德国后印象派的代表。

The famous German painter Leo Assenmacher (1904-1981) was born in Aachen but became famous in Düsseldorf. In this capital city, Assenmacher is not only famous for his paintings, but he also received high praise from the Art industry for his input and support since he joined the Malkasten Artists Association in 1924.

Assenmacher studied murals with his father, Herman Josef Assenmacher, and then entered the Kunstgewerbeschule and Technical University in Aachen, and studied painting with Eugen Klinkenberg. At the age of 20, he left his birthplace to the Düsseldorf Art Academy, where he studied under Professors Dörniger, Spatz, Netzer and Langerand. Later he became a master student under Professor Adolf Münzer. During the school years, Assenmacher has received a large number of orders, and the wonderful murals in the Peter Cathedral in Bonn are also his works.

Assenmacher's paintings are very broad, including the landscape on his journey, portraits, still lifes and nudes. He is even considered to be the representative of the German post-impressionist.
