Hector Aguilar was born in 1905, at the age of thirty he began working as the shop manager for William Spratling at Taller de las Delicias. A sharp businessman, only three years later Aguilar secured the financial backing of a number of investors which enabled him to open his own workshop in 1939. Amongst the backers was Valentin Viduarreta, a talented artist and designer who was responsible for many of Aguilar's early designs.
About 1943, due to wartime metal shortages in the U. S., Aguilar secured a lucrative contract to produce silver jewelry for the large American costume jewelry firm, Coro, and the Aguilar workshop manufactured handmade pieces for them until around 1950.
His financial success, due in large part to superior merchandise combined with business acumen, enabled Aguilar in 1948 to open the Taller Borda, which quickly became one of the premier retail silver outlets in Taxco. Taller Borda sold the full line of first quality sterling jewelry, holloware, flatware and novelties produced at the Aguilar workshops.
The firm prospered for many years until its closure in 1966. Aguilar enjoyed a long retirement and died in 1986.
