donheirman.com is an independent memorial archive. From 1998 to 2021 this domain hosted the website of Don HEIRMAN Consultants, the EMC training and standards consultancy of Donald N. Heirman (1940-2020). After his death on October 30, 2020, the site went offline and the domain lapsed. This project now preserves his professional legacy at its original address and maintains educational content about the EMC standards he helped create.

What happened to the original donheirman.com?

Don Heirman ran his consultancy site at this domain from the late 1990s (an early FrontPage-era site, later rebuilt on WordPress in 2018) until his death. He died on October 30, 2020, at the age of 80; the ANSI memorial notice records the loss to the standards community. The website remained briefly online into 2021, then the domain registration lapsed. This independent project later acquired the lapsed domain to prevent its loss or misuse and to keep his professional record reachable at the URLs the EMC community had linked to for over two decades.

Who maintains this site and where does the content come from?

The site is curated by an independent editorial team. Content comes from three kinds of sources:

• Archived pages of the original site - the Publications, Seminars, and Major services pages are preserved from snapshots of donheirman.com and are clearly labeled as archived material.
• Published records - the Biography is compiled from his own archived biography, the Purdue University Libraries collection, the ETHW profile and IEEE Oral History, Wikipedia, and the ANSI memorial.
• New educational content - the EMC standards section contains current explanatory material written by the editorial team, which is dated and maintained separately from the archival pages.

Is this site affiliated with Don Heirman’s family, IEEE, ANSI, or IEC?

No. This project is not affiliated with, endorsed by, or connected to Don Heirman’s family or estate, the IEEE, ANSI, the IEC, CISPR, Purdue University, or any other organization mentioned on these pages. Organization names appear solely to document his career and to point readers to authoritative sources. The consultancy is closed and nothing on this site is a commercial offer.

What is the editorial policy?

• Facts are cited to sources. Biographical claims trace to his archived site, Purdue Special Collections, ETHW/IEEE records, ANSI, or comparable published records. Where sources conflict or are silent, the claim is omitted rather than guessed.
• Memorial framing, past tense. Pages about Don Heirman and his consultancy are written in past tense and clearly separate archived material from new editorial content.
• No commercial services. The site sells nothing, offers no consulting, and does not present itself as a continuation of Don HEIRMAN Consultants.
• Corrections welcome. If you find an error, email contact@donheirman.com with the correction and, ideally, a source. See the Contact page. Corrected pages have their update date revised.
