## Work at Duck Commander
Si Robertson worked and hunted for Duck Commander, the West Monroe, Louisiana, duck-call company founded by his brother Phil, from his 1993 Army retirement onward.[1](https://duckcommander.com/pages/si-robertson) His workshop assignment was specific and central to the product: making the reeds that go inside every patented Duck Commander duck call.[2](https://www.aetv.com/shows/duck-dynasty/cast/si-robertson) Before the television show, he spent his time making all the reeds for the calls and working with Phil to prepare for each duck season.[3](https://www.simonandschuster.com/authors/Si-Robertson/412528757)
The company had begun decades earlier, when Phil Robertson invented the Duck Commander duck call in 1972 with his brother Si's involvement, and the family's direct-to-video *Duckmen* series, beginning in 1987, extended the business into media before television arrived.[4](https://time.com/7288617/phil-robertson-death-duck-dynasty-christian-conservative-health-tributes-obituary/) Si appears on almost every Duckmen DVD as well as on *Duck Dynasty*.[1](https://duckcommander.com/pages/si-robertson)
## Duck Dynasty
A&E's *Duck Dynasty* premiered in 2012 and followed the Robertson family and their multimillion-dollar duck-call business in the Louisiana swamplands.[4](https://time.com/7288617/phil-robertson-death-duck-dynasty-christian-conservative-health-tributes-obituary/) • [5](https://time.com/2868620/duck-dynasty-ratings-season-6-robertson/) Si became one of the show's most popular characters, portrayed as the eccentric uncle whose war stories with the warehouse crew, much to [Willie Robertson](https://www.edgepedia.org/willie-robertson)'s dismay, usually got everyone behind schedule.[2](https://www.aetv.com/shows/duck-dynasty/cast/si-robertson)
The show's reach was substantial. Its fourth-season premiere drew nearly 12 million viewers, and in April 2013 the series became the most successful program in A&E's 30-year history; four months later that premiere was the most watched nonfiction telecast ever to air on cable television.[5](https://time.com/2868620/duck-dynasty-ratings-season-6-robertson/) Critics described the series as a carefully produced show rather than unmediated reality, with Si's antics, pranks, and one-liners as a fixture of its comic structure.[6](https://www.washingtonpost.com/lifestyle/style/duck-dynasty-the-family-robertson-succeeds-at-reality-by-being-real/2013/08/29/017da8a0-0e95-11e3-8cdd-bcdc09410972_story.html)
## The blue cup
Si's best-known on-screen story concerns a blue cup. While serving overseas, his mother sent him a blue cup; thirty years later, by the account told on the show, it still hung from his back pocket and he continued to drink only from that cup, every day.[2](https://www.aetv.com/shows/duck-dynasty/cast/si-robertson) The story became one of his signature bits on *Duck Dynasty*.
## Books and later work
In 2013 Si published *Si-Cology 1*, an autobiography that reached number one on the New York Times bestseller list; his brother Phil's *Happy, Happy, Happy* was close behind on the same list that year.[2](https://www.aetv.com/shows/duck-dynasty/cast/si-robertson) • [7](https://www.christiancentury.org/article/2013-10/duck-prayer) He followed it with *Si-renity: How I Stay Calm and Keep the Faith*, which, according to its publisher, opens up about how his faith brought him peace through life's ups and downs.[3](https://www.simonandschuster.com/authors/Si-Robertson/412528757)
After retiring from Duck Commander, Si worked on a music career with his band, "Si and the Si-cotics," and practiced his Texas Hold 'Em game, while continuing to hunt each duck season.[1](https://duckcommander.com/pages/si-robertson) Phil Robertson, who had created the Duck Commander call and led the family through the show's run, died in 2025 at age 79 after a publicly disclosed Alzheimer's diagnosis; the franchise continued with the spinoff *[Duck Dynasty: The Revival](https://www.edgepedia.org/duck-dynasty-the-revival)*, centered on Willie and Korie Robertson.[4](https://time.com/7288617/phil-robertson-death-duck-dynasty-christian-conservative-health-tributes-obituary/)
## Personal life
Si lives in West Monroe, Louisiana, with his wife Christine. They have two grown children, Trasa and Scott, each of whom has four sons, for a total of eight grandsons.[3](https://www.simonandschuster.com/authors/Si-Robertson/412528757)
