Oscar Muniz, 80, of Lake Zurich, Illinois passed away on November 28, 2020, surrounded by his family. He was born to parents Benito and Andrea Muniz on January 10, 1940, in Raymondville, Texas. Being one of 10 children, Oscar didn’t have the opportunity for much formal education. He helped provide for his family by working the fields of various farms. He married Minnie, the love of his life, in 1957, and completed their family with a daughter and son. His work ethic and desire to take care of his family led him to find opportunity far from his hometown. He found a home in Lake Zurich in 1967. At that time, Oscar began a career at Adlai E. Stevenson High School. Simply known as “Oscar”, his kindness and eagerness to help made him a beloved fixture at the school by both faculty and students alike. He retired from his Security Guard position in 2007 after 40 years of service. In 2008, he was given the Heritage Award in recognition of how his contributions provided a powerful legacy for the Stevenson community. Oscar was known for his love of family, cooking, and sports. A familiar sight was him commanding a grill to make his famous BBQ chicken. He inflicted his love of football and baseball on all who knew him. An avid Dallas Cowboys fan and Chicago Cubs fan, his last wish for a World Series victory was realized in 2016. His hobbies included fishing, hunting, and coaching youth sports. Oscar is survived by his children Melinda Perry (Lyle) and Oscar Jr (Sharon); grandchildren Rachel, Abel, Adrian, Jacob, Ethan, Eva and great-grandchildren Anabella, Aiden, Lyla. He was affectionately known as “Dad”, “Pops”, “Big O”, “Pappo”, and “Grandpa O”. Oscar was predeceased by his wife, Minnie, his parents, Benito and Andrea, and siblings Maria Inez, Bevo, Aurelia, Jesus (Chuy), San Juana, and Reyes.
