Some context: Matthew Fontaine Maury (January 14, 1806 - February 1, 1873) was an American astronomer, United States Navy officer, historian, oceanographer, meteorologist, cartographer, author, geologist, and educator. He was nicknamed "Pathfinder of the Seas" and "Father of Modern Oceanography and Naval Meteorology" and later, "Scientist of the Seas" for his extensive works in his books, especially The Physical Geography of the Sea (1855), the first such extensive and comprehensive book on oceanography to be published. Maury made many important new contributions to charting winds and ocean currents, including ocean lanes for passing ships at sea.
The war brought ruin to many in Fredericksburg, where Maury's immediate family lived. Thus, returning there was not immediately considered. After the war, after serving Maximilian in Mexico as "Imperial Commissioner of Immigration" and building Carlotta and New Virginia Colony for displaced Confederates and immigrants from other lands, Maury accepted a teaching position at the Virginia Military Institute, holding the chair of physics.  Maury advocated the creation of an agricultural college to complement the institute. That led to the establishment of the Virginia Agricultural and Mechanical College (Virginia Tech) in Blacksburg, Virginia, in 1872. Maury declined the offer to become its first president partly because of his age. He had previously been suggested as president of the College of William & Mary in Williamsburg, Virginia, in 1848 by Benjamin Blake Minor in his publication the Southern Literary Messenger. Maury considered becoming president of St. John's College in Annapolis Maryland, the University of Alabama, and the University of Tennessee. It appears that he preferred being close to General Robert E. Lee in Lexington from statements that Maury made in letters. Maury served as a pall bearer for Lee.  During his time at Virginia Military Institute, Maury wrote a book, entitled The Physical Geography of Virginia. He had once been a gold mining superintendent outside Fredericksburg and had studied geology intensely during that time and so was well equipped to write such a book. During the Civil War, more battles took place in Virginia than in any other state (Tennessee was second), and Maury's aim was to assist wartorn Virginia in discovering and extracting minerals, improving farming and whatever else could assist it to rebuild after such a massive destruction.  Maury later gave talks in Europe about co-operation on a weather bureau for land, just as he had charted the winds and predicted storms at sea many years before. He gave the speeches until his last days, when he collapsed giving a speech. He went home after he recovered and told Ann Hull Herndon-Maury, his wife, "I have come home to die."

Some context: The Triffids were an Australian alternative rock and pop band, formed in Perth in Western Australia in May 1978 with David McComb as singer-songwriter, guitarist, bass guitarist and keyboardist. They achieved negligible success in Australia, but greater success in the UK and in Scandinavia in the 1980s before disbanding in 1989. Some of their best-known songs include "Wide Open Road" (February 1986) and "Bury Me Deep in Love" (October 1987). SBS television featured their 1986 album, Born Sandy Devotional, on the Great Australian Albums series in 2007, and in 2010 it ranked 5th in the book
In 1976 in Perth, high school students David McComb, on acoustic and bass guitars and vocals, and Alan "Alsy" MacDonald, on drums and vocals, formed Dalsy as a multimedia project, making music, books and photographs. They wrote and performed songs with Phil Kakulas on guitars and vocals (all three later in The Blackeyed Susans), then soon became Blok Musik and Logic (for a day). In May 1978, they became The Triffids, taking their name from the post-apocalyptic novel by John Wyndham, The Day of the Triffids. They were soon joined by Andrew McGowan on guitar and Julian Douglas-Smith on piano. When Byron Sinclair joined on bass guitar in September, McComb switched to rhythm guitar. The Triffids began partly in response to the punk rock movement. Writing in his diary as a teenager, McComb traced the band's emergence in Perth:  "On the night of 27 November 1976, a tape was made by Alsy MacDonald, playing a single toy drum, and Dave McComb playing acoustic guitar. The multimedia group 'Dalsy' had come into being. Dalsy went on to make several remarkable tapes (mainly of original material): The Loft Tapes, Rock 'n' Roll Accountancy, Live at Ding Dongs, Bored Kids, Domestic Cosmos, People Are Strange Dalsy Are Stranger, Steve's and the seminal punk work, Pale Horse Have a Fit ... Dalsy did paintings, sculptures and poetry, and wrote a book named "Lunch". They were tinny and quirky, obsessive and manic, versatile and productive. They were also immensely unpopular ... The members of Dalsy grew to hate their audience. They still do, and this hate is an integral part of their music. Dalsy split up towards the end of 1977 ... They launched into 1978 as Blok Musik, with their famous Blok Musik tape ... In April, they played at the Leederville Town Hall Punk Fest, alongside Perth's punk rock contingent but, as usual, no one danced. After that they went home and metamorphosised into Logic. Within a day they changed their minds, and metamorphosised into the Triffids."  Between 1978 and 1981, McComb had written over 100 original songs and The Triffids had recorded and independently released six cassette tapes, simply called, 1st (1978), 2nd (1978), 3rd (1979), 4th (1979), Tape 5 (1980) and Sixth (1981) (see List of The Triffids Cassettes). By 1979, Kakulas and Sinclair had left and were replaced by David's older brother, Robert McComb on violin and guitar, and Will Akers on bass guitar, and in 1980 Margaret Gillard joined on keyboards. At year's end, the band won a song competition run by the Western Australian Institute of Technology (now Curtin University) Student Guild's radio show on 6NR (now Curtin FM), and in July 1981 they released their first single, "Stand Up", on the Shake Some Action label. MacDonald had briefly left the band for two months, and the single was recorded with Mark Peters as drummer.
