History
During the early Spring 1986 semester, Baltazar Mendoza-Madrigal began to explore the idea of establishing a Latino based Fraternity. After months of intensive research, Baltazar Mendoza-Madrigal called a special meeting on Monday, March 7, 1986 with some of the Latino students at the Chicano Indian American Cultural Center in the University of Iowa. The purpose of the meeting was to discuss the need and feasibility of creating a new social Fraternity with an emphasis on the Latino Culture.
At that point in time, the student body at the University of Iowa was predominantly Caucasian. In addition, the Latino community on campus was divided into different social groups. As a result, the students who attended the first meeting wanted to solidify and unify the Latino community. Furthermore, the students wanted to promote a positive image of Latinos in the University.
After the first meeting, the enthusiasm in favor of the Fraternity was so encouraging that the word spread throughout the University of Iowa. Everyone knew that something special was about to take place. On Friday, April 4, 1986, the members finalized the philosophy of the Organization. Hence, April 4, 1986, is the official founding date of the Fraternity.
The Eighteen Founding Fathers founded Sigma Lambda Beta with the following principles in mind BROTHERHOOD, SCHOLARSHIP, CULTURAL AWARENESS and COMMUNITY SERVICE. Our Founding Fathers had a dream and VISION that our Honorable Fraternity could promote a positive image of the Latino Community in the University of Iowa and other Universities located in the Midwest region of the Nation through scholastic achievements, eternal Brotherhood, the dissemination of our unique and rich culture, and service to our community. Furthermore, as our Honorable Fraternity expanded and grew in the late eighties, the new and younger Brothers worked hard by trying their best to carry out the founding principles of our Organization. Hence, those Brothers tried to carry the torch and VISION of our Founding Fathers. The Brothers who pledged in the early nineties, mid nineties, and late nineties are keeping the light shining and working hard to promote a positive image of our people and our community throughout the Nation. The Brothers have the VISION that members of our community will graduate from college, pursue a Graduate Program, join the professional work force, help the younger members of our community, serve our community, and educate others through cultural awareness
