eaH Olelo Channel 53 May Program:

History of the Honolulu Fire Department by Sam Dannaway FPE


“A study of the history of the Honolulu fire department is a study of the culture, society, politics, and changes of the time of Honolulu itself. A fire department doesn’t grow in a vacuum, it develops in response to the changes in the society, culture, and especially the politics that surrounding it. It can best be stated by the theoretical physicist Stephen Hawking’s, “It is the past that tells us who we are. Without it we lose our identity.” 

Showings: Wednesday May 10 6:00 pm and Sundays at 1:00 pm
