Wojciech M. Seweryn, a 70-year-old artist, was killed in the crash that took the lives of 97 people, Chicago's Polish Consul General Zygmunt Matynia told NBC 5.
The plane crashed while navigating through heavy fog at 2 a.m. CT, killing Polish President Lech Kaczynski and some of the country's highest military and civilian leaders.
The group was headed to an event marking the 70th anniversary of the Katyn massacre of thousands of Polish officers by Soviet secret police.
Seweryn, whose father was killed in the massacre, was actively involved in a movement to create a monument in Niles, Matynia says.
Wojtowicz's daughter, Anna, said she last spoke to her father Friday night, hours before he boarded the flight.
"He said this was the best trip he ever had," she said.
President Kaczynski was planning to visit Chicago on May 1st to commemorate Polish Constitution Day, according to Matynia.
People can pay respects to the victims at the Chicago Polish Consulate (1530 N. Lake Shore Dr) by signing a book.
