I'm sorry but I couldn't reply to your message because it says that you aren't found. It's weird, I know. Here is the info you asked for.

Alfred J. Brown was the first black firefighter, in the 1890s. Taylor and Morenci served in the 1930s. The info I have is from a book called Detroit Firefighters 1865-2005 A Pictoral History of the People by Cheryl Anderson.
I could try scanning the page for you as it does have a picture of Mr. Brown. I don't have any other info on Mr. Brown. if you can get the book, it's a wonderful pictoral history with every FFs picture in there and some intersting photos. If you'd like me to scan the page, I do need your email.
