Context paragraphs:
Ann Arbor (automobile): The Ann Arbor was an automobile manufactured in Ann Arbor, Michigan, by the Huron River Manufacturing Company from 1911–12.  The Ann Arbor was a dual-purpose vehicle, which could be converted from a private car, to a small pickup.  Automotive production, however, never succeeded in Ann Arbor.  The ill-fated Huron River Manufacturing Company, later the Star Motor Company, did not survive the fierce competition of the burgeoning auto industry.  The high cost of living in Ann Arbor meant higher wages and the distance from Detroit increased the cost of materials to a point where profit disappeared.

Interact Home Computer: The Interact Home Computer is a rare, very early (1978) American home computer made by "Interact Electronics Inc" of Ann Arbor, Michigan.  It sold under the name "interact Model One home computer".  The original Ineract Model One computer was designed by Rick Barnich and Tim Anderson at 204 E. Washington in Ann Arbor, then moving to an office in Georgetown Mall on Packard St in Ann Arbor.  Interact Electronics Inc was a privately held company that was funded by Hongiman, Miller, Swartz and Cohn...a lawyer firm out of Detroit.  The President/Founder of Interact Electronics Inc was Ken Lochner, who was one of the original developers of the BASIC language based out of Dartmouth college.  Ken had started Interact Electronics Inc after a successful startup known as ADP Cyphernetics, the original computer time share company in Ann Arbor, now known as ADP Network Services.  Only a few thousand Interacts were sold before the company went bankrupt.  Most were sold by the liquidator "Protecto Enterprizes" of Barrington, Illinois through mail order sales.  The Interact Model One Home Computer debuted at the Consumer Electronics Show in Chicago in June 1978 at a price of $499.  The majority of sales were thru Mail Order houses and you could buy it off the shelf at Highland Appliance in the Detroit, MI area and Newman Computer Exchange in Ann Arbor.  Probably the most successful application available for the Interace was a program called "Message Center".  With it, a store could type in whatever message they wanted to appear scrolling on a TV screen...like Advertisements, or welcoming messages to guests in an office.  Although it was mostly a Game machine at the time with games such as Showdown, BlackJack and Chess, there was also BASIC programming where users could create their own programs in the BASIC computer language.  Customers began hooking up Interact to control everything from lights in their house, to a Chevrolet Corvette!

Ann Arbor Bus Depot: The Ann Arbor Bus Depot was an intercity bus station located at 116 W. Huron in Ann Arbor, Michigan.  It was built in 1940 as the Eastern Michigan Motorbus Terminal, and operated as a bus station until its demolition in 2014.  It was designed by the Cleveland-based architects Banfield and Cumming, in partnership with Ann Arbor architect Douglas Loree, in an Art Deco style.  Between 1988 and 2001, it was listed as an Individual Historic Property on the Ann Arbor Register of Historic Places.  The Bus Depot was demolished in 2014 to make way for a six-story, 110-room hotel on the property, although its facade and marquee are being preserved and will be incorporated into the new hotel.  It served as Ann Arbor's Greyhound station until shortly before its demolition in 2014.  It was also both the last surviving example of Streamline Moderne architecture and the last public Art Deco structure in Ann Arbor.

William S. Maynard: William Sumner Maynard (April 25, 1802 – June 18, 1866) was a politician from the U.S. state of Michigan, who served as mayor of Ann Arbor, Michigan from 1856 to 1858 and again from 1865 to 1866.  Maynard was born in Berkshire County, Massachusetts.  He suffered from severe depression and (while still Mayor) committed suicide in 1866 by an overdose of (laudanum) morphine.  Long notes of explanation were found in the pockets of his dressing gown, detailing Maynard's struggles with "The Evil One" (a synonym for Satan).  The notes were published verbatim in Ann Arbor's several weekly newspapers.  Maynard had been Ann Arbor's biggest land developer, a member and organizer in 1836 of the Ann Arbor Land Company, which acquired the former Henry Rumsey farm east of town, conveying 40 acres thereof to the newly formed State of Michigan as the site of the future University of Michigan, while hoping to profit by subdividing and selling town lots adjacent to the campus.  Maynard also developed much of the land west of Ann Arbor's Main Street, as far west as the present Seventh Street.  His own landmark dwelling was on the northwest corner of Main and William Street, and the estate stretched west to the present Ashley street, and halfway up the block to Liberty.  For many years he owned a grocery, drug and dry-goods store and was said to be the wealthiest man in Ann Arbor at the time of his suicide.  His grave is in Forest Hill Cemetery in Ann Arbor.

Ann Arbor Argus: Ann Arbor Argus was a radical, counterculture biweekly underground newspaper published in Ann Arbor, Michigan, starting January 24, 1969, and lasting until mid-1971.  It was founded and edited by underground journalist Ken Kelley (1949–2008), a 19-year-old University of Michigan student who lived at the Trans-Love Energies commune off campus.  The paper was started by Kelley and a friend out of his apartment, but soon moved into well-furnished office space provided by the Episcopal Church half a block from the university campus, in the basement of Canterbury House, a church-run coffee-house.  The "Argus" was closely connected to John Sinclair's radical White Panther Party and the Students for a Democratic Society.  It was a member of the Underground Press Service and the Liberation News Service.  It had no connection to the earlier 19th century Ann Arbor newspaper of the same name.  Circulation in 1969 was reported at 14,000 copies.
