What is now known as Texas Scottish Rite Hospital for Children (TSRHC) is officially chartered on October 6, 1921 by a group of five community leaders who are also members of the Masonic Fraternity. They are named as the first Board of Trustees of the hospital.

The Board of Trustees approaches Dallas orthopaedic surgeon Dr. William Beall Carrell about treating children with polio free of charge. Dr. Carrell offers his services and clinic space and becomes the hospital's first chief of staff (COS).

As word spreads throughout Texas and the caseload increases, the clinic has treated 500 patients and has 1,000 applications waiting from 150 Texas counties. The clinic moves to the new and larger Dallas Medical Arts building in downtown Dallas.

The caseload continues to rise and Texas Masons determine that a hospital facility is needed to accommodate future growth. Texas Scottish Rite Hospital for Crippled Children is built on three acres in Dallas’ Oak Lawn area at the corner of Welborn Street and Sylvester Street (now Scottish Rite Way). The original structure is a two-story red brick building with a 15-bed patient ward.

The Texas Scottish Rite Masons assume financial responsibility for the hospital. The Board of Trustees establishes an endowment fund to ensure the longevity of TSRHC’s work.

The total number of patients treated reaches 14,000.

Four years later, the total number of patients treated has nearly doubled to more than 27,000.

Dr. Brandon Carrell succeeds his father as TSRHC’s second Chief of Staff. His father, Dr. William B. Carrell, served the hospital from its founding in 1921 until his death in 1944.

The Salk and Sabin vaccines virtually eradicate polio in North America, allowing TSRHC medical staff to expand treatment in a wide range of pediatric orthopaedic disabilities caused by disease, accidents and congenital conditions such as scoliosis and clubfoot.

Pediatric neurologist Dr. Lucius “Luke” Waites joins the staff and develops a center to evaluate and treat children with learning disabilities, specifically dyslexia. In 1968, at the invitation of Dr. Waites, the World Federation of Neurology meets at TSRHC and develops the first consensus medical definition of dyslexia.

Ground is broken on a new six-story, 400,000-square-foot facility across the street from the original hospital building. It opens in 1977.

Current TSRHC Chief of Staff, Dr. J. A. "Tony" Herring, is appointed. He continues to work closely with Dr. Brandon Carrell until Dr. Carrell's death in 1981. In the hospital’s 90 years of service to children, there have been just three Chiefs of Staff.

TSRHC’s pediatric orthopaedic fellowship program is initiated to allow orthopaedic surgeons to pursue additional specialized training. Since that time, 130 orthopaedic fellows representing 33 states, Puerto Rico and Canada have trained at TSRHC. In addition, more than 20 surgeons from countries throughout the world have trained at TSRHC through the hospital’s international fellowship program.

The annual TSRHC Amputee Ski Trip is established to give 14 teenage patients the opportunity to learn to ski at the renowned National Sports Center for the Disabled in Winter Park, Colo. The event comes six years after the hospital launched its own Prosthetics department to custom build prostheses for its patients.

The TSRH® Spinal Implant System, developed in the hospital’s research laboratory to correct a range of spinal deformities, is introduced at the annual meeting of the American Academy of Orthopaedic Surgeons. It becomes the most widely used spinal implant system in the world.

The first Tartan Golf Classic is held at Brook Hollow Golf Club. Since its inception, this annual golf event has raised more than $4 million for TSRHC.

The number of active volunteers at the hospital reaches 500. Since the founding of the Auxiliary in 1921, nearly 3.5 million volunteer hours have been contributed to the hospital by these dedicated individuals who now number more than 800.

Dr. John Birch, assistant chief of staff, begins performing the Ilizarov procedure to lengthen and straighten bones of TSRHC patients.

Researchers at TSRHC develop the TRUE/LOK® External Fixation System, a patented modification of the Ilizarov device for the lengthening and straightening of bones.

The hospital celebrates its 75th birthday. TSRHC’s now widely recognized crayon logo and colorful campus signage are debuted as part of the hospital’s commemorative 75th year.

The total number of patients treated at the hospital surpasses 100,000, almost 10,000 for scoliosis.

The first Treasure Street event is held at TSRHC, raising more than $150,000 in proceeds. Since its inception, Treasure Street has raised more than $8.5 million benefiting the hospital’s Tuberous Sclerosis Complex (TSC) Clinic and many other hospital programs. In 2010, Treasure Street celebrated its most successful event to date, generating more than $1 million in proceeds during one single year.

The four-acre James F. Chambers, Jr., Youth Fitness Park, named in honor of a longtime hospital leader and trustee, opens on the TSRHC campus to help children of all abilities reach their potential.
