WASHINGTON, D.C. (WDVM) — George Washington University Assistant Professor Paul Tschudi died in a house fire in Northeast D.C. on Wednesday, April 7.

D.C. Fire and EMS responded to the call at the 1500 block of Monroe Street around 4 a.m. The Metropolitan Police Department said the 73-year-old man was found unconscious and unresponsive on the second floor of the building. Officials said Tschudi’s dog died as well.

According to Tschudi’s bio on the G.W. website, he was an Assistant Professor in Health Sciences. He was also the Founding Director of the Grief, Loss and Life Transitions Graduate Certificate in the Graduate School of Education and Human Development.

The bio goes on to say that Tschudi owned a private grief counseling practice and served as Executive Director of the St. Francis Center (now the Wendy Center).

A statement from George Washington University said, “The George Washington University mourns the passing of Paul Tschudi, long time faculty member and alumnus of our Graduate School of Education and Human Development. … Paul, a veteran, contributed extensively to the lives of veterans transitioning to civilian life, including GW students. This was a life passion of his, and he was honored for this work at the university. He was a caring, kind and generous colleague and friend who will be truly missed.”

The fire was knocked down around 5 a.m. and the investigation into the cause is ongoing. Mitchell Kannry, Deputy Fire Chief in charge of Fire Prevention Division, stated they believe the fire was accidental and are working to determine whether smoke detectors were present.

Officials say the fire did not affect nearby homes.

Fire officials spent Wednesday afternoon going door-to-door delivering smoke detectors to residents who need them and educating them on the importance of working smoke detectors.
