The Art program at Crestwood School has yet again had the privilege of welcoming the world renowned engineer and model maker, Valeri Ivanov. His unique collection of scale working models based on the historical sketches of Renaissance engineers as well as his own inventions have been a part of some of the largest science museums in the world. The collection of machines created by Mr. Ivanov is interactive and provides a fascinating insight into the lives of our ancestors. His intention in creating the collection is to bring to light the fascinating history of the time and to prompt interest and conversation on the topic of engineering. Valeri brings to life the inventions of Leonardo da Vinci and other prominent thinkers of the time and through them ignites the curiosities of children and adults alike.
