William Jackson Brack was the first mayor of Orlando, Florida from 1875 to 1877.

He was born to John, 1800-1887 and Elizabeth(Eliza) McCall 1811-1879 in Georgia on June 17, 1837. Grandson of Benjamin "R. S." BRACK and Christiana FIELDS. Brother of Lucinda Brack; Francis Brack; Washington Brack; Henrietta Brack; Isabelle Brack Lastinge, Queen Brack, Ann Victoria Brack and Augustus Brack

He married firstly to the former Olive Chancey (1838 - 1864) of Clinch County, Georgia, by whom he had two sons who died young. The Bracks removed to Alexandria, Louisiana before the outbreak of the Civil War. During that conflict, the future mayor served in Company C of the 27th Louisiana Infantry Regiment. He was taken prisoner at Vicksburg, Mississippi on July 4th 1863 and paroled at Shreveport, Louisiana on June 8 1865.

After the war, the widowed Brack came to Florida, where he married his second wife Amy (July 5, 1847 - May 25, 1880). They had three daughters before her untimely death

It is unclear exactly when Brack settled in the Orlando area. He was certainly there by October 16, 1873, when he was mentioned as guardian ad litem for the orphans of Mrs. Lucinda Hughey Terrell in a lawsuit filed in the circuit court of Orange County, Florida.

In 1875, when Orlando was formally incorporated, Brack was elected its first mayor. He was subsequently re-elected to a second one-year term.

After leaving office, the former mayor remained in the Orlando area as a farmer and fruit grower until at least 1880. He was married there to his third wife Eliza A. Tyson on March 6, 1881.

The Bracks left Orlando to live on the north shore of Lake Tohopekaliga where they operated a general store and sawmill at "Brack's Landing." From that point, he also captained a 35-foot sidewheel steamboat called "Spray" along the inland canals that connected the Kissimmee River valley to Fort Myers, Florida on the Gulf of Mexico.

The former mayor retired to a cattle ranch near Narcoossee, Florida, where he died.
