Guinness World Records does not work alone. Helping us to assess superlative achievements across as wide a spectrum as possible is a team of world-leading experts from all manner of disciplines. These range from archaeologists to zoologists and pretty much everything in between.
Norris McWhirter, who founded The Guinness Book of Records in the 1950s, described this collaborative process as the “extraction of the ‘ests’ from the ‘ists’”. In other words, we strive to affirm the largest, fastest and oldest with those that know their fields inside and out, whether that be dendrologists (trees), gerontologists (ageing) or funambulists (tightrope walking).
