The American Civil Liberties Union of Iowa will celebrate its 75th anniversary on Saturday with an event at the University Athletic Club.

The event will feature the ACLU’s national executive director, Anthony Romero, and will include the presentation of the 2010 Louise Noun Civil Liberties Award to five couples who served as plaintiffs in the historic marriage equality case Varnum v. Brien, in which the Iowa Supreme Court ruled that the Iowa Constitution’s equal-protection clause forbids the denial of civil marriage to same-sex couples.

The event is scheduled to begin with a reception at 5:30 p.m., followed by the dinner and program at 7 p.m. Tickets for the dinner and program — which are open to the public — are $45.
