It's the 25th anniversary of the Ann Arbor Hands-On Museum! In celebration, and in conjunction with the Library's Figure It Out summer reading program, AADL and AAHOM are hosting several science lectures at the downtown Library. In the first lecture, nationally-known Edison expert John Bowditch will discuss two great inventors of the 20th century. Nikola Tesla and Thomas Edison are known not only for their inventions, but also for their intense rivalry. This event will be taped for future broadcast on Community Television Network. A 25th Anniversary Ann Arbor Hands-On Museum Historical Exhibit will be displayed in the lower level of the Library through July 21. John Bowditch is the current Director of Exhibits at the Ann Arbor Hands-On Museum. He has also served as Curator of Industry at Henry Ford Museum & Greenfield Village for 21 years and as the Director of the Lowell Museum in Lowell, Massachusetts. A published author, Bowditch has appeared on the BBC and History Channel as an expert on Thomas Edison. Additional science lectures in this series will take place in July.
