Wellington: US President Donald Trump, in his inauguration address on Monday, made several false and misleading claims including his declaration that Americans "split the atom".
This prompted vexed social media posts by New Zealanders, who said the achievement belonged to a pioneering scientist revered in his homeland.
In his speech, Trump said: Americans are explorers, builders, innovators, entrepreneurs and pioneers...They crossed deserts, scaled mountains, braved untold dangers, won the Wild West, ended slavery, rescued millions from tyranny, lifted millions from poverty, harnessed electricity, split the atom, launched mankind into the heavens and put the universe of human knowledge into the palm of the human hand.
Ernest Rutherford, a Nobel Prize winner known as the father of nuclear physics, is regarded by many as the first to knowingly split the atom by artificially inducing a nuclear reaction in 1917 while he worked at a university in Manchester in the United Kingdom.
The achievement is also credited to English scientist John Douglas Cockroft and Ireland's Ernest Walton, researchers in 1932 at a British laboratory developed by Rutherford. It is not attributed to Americans.
Trump's remarks provoked a flurry of online posts by New Zealanders about Rutherford, whose work is studied by New Zealand schoolchildren and whose name appears on buildings, streets and institutions. His portrait features on the 100-dollar banknote.
"Okay, I've gotta call time. Trump just claimed America split the atom," Ben Uffindell, editor of the satirical New Zealand news website The Civilian, wrote on X. "That's THE ONE THING WE DID."

New Zealand politician Nick Smith, the mayor of Nelson, where Rutherford was born and educated, said he was "a bit surprised" by the claim.
"Rutherford's groundbreaking research on radio communication, radioactivity, the structure of the atom and ultra sound technology were done at Cambridge and Manchester Universities in the UK and McGill University in Montreal Canada," Smith wrote on Facebook.
Smith said he would invite the next U.S. ambassador to New Zealand to visit Rutherford's birthplace memorial "so we can keep the historic record on who split the atom first accurate."
A website for the U.S. Department of Energy's Office of History and Heritage Resources credits Cockroft and Walton with the milestone, although it describes Rutherford's earlier achievements in mapping the structure of the atom, postulating a central nucleus and identifying the proton.
