Correction

The Illinois Mathematics and Science Academy was established in 1985, not 1986. Official IMSA sources say 1986 was the year the school opened its doors, not the year it was founded.

Full reasoning

Official Illinois Mathematics and Science Academy history distinguishes between establishment and opening:

  • IMSA's founders page says Leon Lederman helped lead the effort to create IMSA and that "in 1985, IMSA was established by the Illinois General Assembly".
  • The same official page then says "In 1986, IMSA opened its doors".
  • IMSA's Lederman tribute page repeats the same timeline: "IMSA was created in 1985 and opened its doors in 1986."

So the article's wording is inaccurate on the date: 1986 was the opening year, not the founding/establishment year. A more accurate version would say Lederman helped found or create IMSA in 1985, and that the academy opened in 1986.
