Dr. D. C. Neckers, our Founder and CEO

Spectra Group Ltd., Inc. was founded in 1991 by renowned US photochemist Dr. Douglas C. Neckers. The corporation was originally chartered to create 3D models from medical image data, as in CT or MRI scans, for surgical planning using stereolithography. Neckers’ laboratories at the Center for Photochemical Sciences, Bowling Green State University, were the first in the world to introduce this technology.

Neckers’ career was mostly associated with Bowling Green State University and the Center for Photochemical Sciences that he founded there. His Bowling Green years have been nicely captured in an article published in the fall, 2012, BGSU Magazine. His recent academic interests have been similarly portrayed in an article from Allegheny College. Some of many students and colleagues are shown in the picture to the right.

Neckers’ research interests are broadly in organic chemistry, but more narrowly in photochemical reactions and photopolymerization processes. His labs in the Center were the first in the world to print, using stereolithography, 3 D models from CT scans, and MRI scans.

The picture below shows him holding a skull printed from a CT scan of one of the mummies owned by the Toledo Museum of Art.

The ‘Mummies’ story has been told nicely in ‘KMT – A Modern Magazine of Ancient Egypt’: KMT – A Modern Journal of Ancient Egypt. Spring, 2001: A Mummy Comes to Life in Toledo, by Sandra Knutsen; p. 36.
