:''For the 17th-century English colonist in Massachusetts, see Samuel Maverick (colonist) (1602–1670).''
Samuel Augustus Maverick (July 23, 1803 – September 2, 1870) was a Texas lawyer, politician, land baron and signer of the Texas Declaration of Independence. His name is the source of the term "maverick," first cited in 1867, which means "independently minded." Various accounts of the origins of the term held that Maverick came to be considered independently minded by his fellow ranchers because he refused to brand his cattle, though it might have instead reflected a lack of interest in ranching. Unbranded cattle which were not part of the herd came to be labeled "mavericks". He was the grandfather of Texas politician Maury Maverick, who coined the term gobbledygook (1944).
