This information seems to be at odds with official records Adolphus Albert Le Sueur (as listed) was born and died on this dates but for him to Matriculated in 1859 means he would have been 10 years old which seems debatable.
After graduating with a Bachelor of Arts degree as 21st wrangler in 1863,[3] he trained in astronomy under John Couch Adams at a local observatory.
[2] Le Sueur wrote that he felt he had little "special knowledge" in the field of astronomy, but would endeavour to prove himself capable to his clients.
In the meantime, he was coached in celestial photography by Warren de la Rue and immersed himself in the intricacies of building the telescope.
[4] In 1868, he supervised its transportation to and erection in Melbourne; despite being a talented astronomer, drawer and photographer, he clashed with Robert Ellery, the telescope's director, and returned home in 1870.
