Martin Ebbertz (born 1962 in Aachen) is a German writer of children's books. He grew up in Pruem (Eifel), and studied Germanistik, Philosophy, and History in Freiburg, Munster and Frankfurt. He lived and worked as a freelance writer first in Frankfurt/Main, then five years in Thessaloniki, Greece. Since spring 2000 Martin Ebbertz has lived with his wife and two children in Boppard on the Rhine River. His first children's book "Josef, der zu den Indianern will" appeared in 1992. His best known book is "Der kleine Herr Jaromir" (2002), which was also translated into Dutch and Chinese.

Little Mr. Jaromir lives on the sixth floor. Each time he gets into the lift, he jumps as high as he can and presses a button. He usually reaches the fourth floor and walks up the last two flights.
Mr. Jaromir is a child of fortune. He blows the biggest bubbles, he wins a raffle, and has many adventures. He meets up with a trolley thief in a supermarket, and for three days he is trapped in the lift, where he decides to plant tomatoes - a special variety needing little sunlight.
A charming, clever and original story, much praised by the press and awarded several prizes.
