Paderewski Symphony Orchestra's network

19 people5 organisationsi19 people and 5 organisations on this map.The large node is the subject of this page. Solid lines are what the register itself records (19). Violet dotted lines (9) are likely: the same full name sits on the current board of another organisation in the same register and region. Form 990 filings give names without a person identifier; SEC insider filings carry a CIK. It may be a different person.

The board

19 listediTime on the board is observed from the annual filings: the IRS files no appointment date, so the bar counts years from the first filing the person appears on - a lower bound, not a filed start date. Names are exactly as filed. The IRS publishes no person identifier, so this edition does not yet link a person across organisations in the tables. The network map shows same-name matches as likely links only, never as confirmed.Time served and departures are observed across annual filings. Observed time served is a lower bound - a member may have joined before the first year on record. The organisation reported 21 voting members of its governing body on its latest Form 990 Part VI, which matches the board listed here.
