The Museum of South Texas History will host two Sunday Speaker Series Online presentations on Feb. 28 on Facebook Live.

Pioneers come in many forms—sometimes as entire communities with a unique founding story. The All-America City of Pharr, which was incorporated in 1916, is a central community at the heart of the historic Rio Grande Valley. Sugarcane grower Henry Newton Pharr, who was also an engineer and manufacturer, along with his partner John C. Kelly, founded the city of Pharr for their interest in establishing a sugarcane empire.

Romeo Rosales Jr., the author of “Images of America: Pharr,” will share Pharr’s foundation and incorporation, stories on the National Guardsmen in the 1910s, agriculture history, and law and order at 2 p.m. on Feb. 28 on Facebook Live. Copies of Rosales’ 2014 publication of “Images of America: Pharr” are available for purchase in the Museum Store.

Rosales Jr. is a fourth-generation Pharr native. He holds a bachelor’s degree in history from The University of Texas-Pan American (now UTRGV) and a Master of Library Science degree from Texas Woman’s University. Currently, Rosales is the Head of Collections & Acquisitions Librarian at BiblioTech Public Library in San Antonio. BiblioTech is the first-ever all-digital public library in the world. He is the only librarian in the country to hold such a position.

On the same day at 4 p.m., Sandra Tumberlinson and Lonnie Davis from the Callandret Black History Museum in San Benito will discuss the history and importance of the Callandret Schoolhouse, a school established in 1952. It was built on land donated by the Callandret family.

Tumberlinson is a founding member of the San Benito Historical Society and the standing Treasurer. She is also a founding member of the Museum of San Benito. She has dedicated her life to the preservation of local history and is on the Board of Directors at Callandret Black History Museum.

Davis is a member of the Village in the Valley Black History and Celebrations Committee and a Board Member of the Callandret Black History Museum of San Benito. His involvement in the Rio Grande Valley community extends from volunteer work with the Westside Center to presentation of Black History to local schoolchildren. Davis was one of the first Black students to graduate from Harlingen High School in 1961.

This named endowment was created by her family to honor her memory and to continue providing educational opportunities for the community.

About Museum of South Texas History
The Museum of South Texas History is accredited by the American Alliance of Museums. It is located downtown Edinburg at 200 North Closner Boulevard on the Hidalgo County Courthouse square. Founded in 1967 as the Hidalgo County Historical Museum in the 1910 Hidalgo County Jail, the museum has grown over the decades through a series of expansions to occupy a full city block. In 2003, following the completion of a 22,500 square foot expansion, the museum was renamed the Museum of South Texas History to better reflect its regional scope. Today, the museum preserves and presents the borderland heritage of South Texas and Northeastern Mexico through its permanent collection and the Margaret H. McAllen Memorial Archives and exhibits spanning prehistory through the 20th century.
