Hazel’s story is one of passion and perseverance. In 1951, alongside her first husband, Glen Sigafoose, she co-founded Sig Manufacturing Company in Montezuma, Iowa. What began as a small business operation selling balsa wood to local modelers soon grew into a company known around the world and built up by Hazel’s hard work, precision, and belief in the joy of flight. 

A licensed pilot, flight instructor, and aerobatic performer, Hazel brought the same spirit of adventure to the air that she shared with the modeling community. Whether she was at the controls of her clipped-wing Cub or mentoring a new modeler, she brought boundless enthusiasm and an encouraging spirit to everything she did. Those who met her remember her energy, warmth, and fearless love of flying—qualities that helped define not only her life, but the heart of the hobby she helped shape.  

Hazel’s story is a testament to what can happen when a love of flight takes root and never lets go. Her legacy continues to soar in every model built, every pilot inspired, and every person who looks to the sky and dreams of flying.

  1. Thank you for covering this news. Across 55 years of my building flying airplanes, I know of very few that contributed so much to model aircraft. Thank you Hazel and all the folks at Sig for great products.
