Ada Sawyer Garrett (1856–1938) was a late 19th-century Chicago socialite.
The daughter of Dr. Sidney Sawyer and the former Elizabeth Butterfield, Ada was a popular society debutante. She married T. Mauro Garrett, a railroad official. She and her mother subdivided 80acres of land on the Northwest Side of Chicago that had been purchased by Ada's grandfather, attorney Justin Butterfield, to create Logan Square, a genteel neighborhood of mansions.
When Ada Garrett's husband died in 1900, she went into seclusion, devoting her time to managing her finances. She died in 1938, leaving $2,250,000 to the Chicago History Museum, the Art Institute of Chicago, the University of Chicago, a number of Chicago hospitals and homes for the poor, disabled, and orphans, and to relatives.
Ada Street and Ada Park in Chicago are named for Ada Sawyer Garrett.[1]
