History
Erath is named after August Erath (18 March 1843 - 11 September 1900) who emigrated from Switzerland to New Orleans in 1860 and was a bookkeeper in the breweries. He moved to New Iberia in 1876 and erected a brewery there. Erath was later mayor of New Iberia and began to develop land in the Erath area. Although August Erath never lived in Erath, he was close to railroad officials, which brought forth a great business venture for him.  Later, Erath built a seltzer water factory in New Iberia and an ice plant in Abbeville. In 1884, he started a hardware business and purchased land located in this area.

In 2005, storm surge forced inland by Hurricane Rita flooded most of the town. Water in most parts of town was up to six feet deep.

Economy
Erath is home to Henry Hub, an important junction of natural gas pipeline systems. Natural gas prices in North America are more or less set at this junction.

The "Henry" hub is so named for its location in the Henry hamlet of Erath, which was named after the Henry High School that stood there until damage from flooding due to Hurricane Rita forced its closure and demolition. This school was named for its benefactor, William Henry, who originally immigrated from Copenhagen, Denmark as Ludwig Wilhelm Kattentidt, circa 1840, then dropped the surname and used his father's middle 'Heinrich' for his surname of Henry. There are Henry descendants in the area to this day.

It was customary for benefactors to sponsor schools; there were quite a few similarly sponsored schools in Vermilion Parish around that time. Being that long ago and in a rural area, with schools sometimes sponsored even in homes, there was great variation in what was offered to how many, and it often changed over time. Records say that the Henry school was founded in 1877, and apparently became a high school in 1896 because it celebrated its centennial in 1996.

In 1992, the Vermilion Parish school district reorganized the schools. Students transferred to Erath High, and Henry High became an elementary school. Then on September 24, 2005 (less than a month after Hurricane Katrina), Hurricane Rita smashed the parish and ruined the school. The area was also hit hard three years later by Hurricane Ike, and the main building was finally razed around March 2009. Likewise, St. John Catholic Church across the street had its rectory damaged; it is being replaced with a new building elevated to meet new flood standards as of early 2014.

When land for the Henry school was bequeathed, it was stipulated for education into perpetuity, or to be returned to the heirs.  The gymnasium was salvaged and is still used by the school district to this day. A Google Earth comparison of, for example, Feb. 28, 2006 to April 23, 2012, at the intersection of Highways 330 and 689 shows a parking lot where the main school was, and the church's rectory gone, but the gymnasium in clear use by child sports organizations and other groups.
