Kay Rasmus Nielsen was a Danish illustrator who was popular in the early 20th century. Nielsen is also known for his collaborations with Disney for whom he contributed many story sketches and illustrations. 

Kay Nielsen was born in Copenhagen into an artistic family on 1886. Both of his parents were actors. His father was the Theater director and his mother was one of the most celebrated actresses of her time. Kay Nielsen began studying art in Paris when he is 18 years old and He studied at Academie Julian and Academie Colarossi from 1904 to 1911. Then lived in London, England from 1911 to 1916.

He debuted as artist and published “In Power and Crinoline” when he is 27 years old.

The colour images for both “In Powder and Crinoline” and “East of the Sun and West of the Moon” were reproduced by a 4-colour process, in contrast to many of the illustrations prepared by his contemporaries that characteristically utilized a traditional 3-colour process. 

After the war, he returned to Copenhagen and he began stage design’s work when first in the 1920s.

He published “Fariy Tales of H.Andersen” when he is 38 years old, “Hansel and Gretel and Other Stories” when he is 39 years old, “Red Magic” when he is 44 years old.

In 1950s he went to the United States and he work on that art of Disny movie “Fantasia”.

In 1957s he died in Los Angeles when he is 71 years old.

~Impression~ I like Kay Nielsen’s Illustration very much. His Illustration is delicate and beautiful. It is modest shade, but it has a very strong presence and draws its eyes. I thought it was awesome not only an Illustration but also for work in the stage design’s. I would like to follow his extensive leaning attitube example.
