Mary Ann Horton Biography

Mary Ann Horton is one of the most popular and richest Computer Scientist who was born on November 21, 1955 in Richland, Washington, United States. Mary Ann Horton (born Mark R. Horton on 21 November 1955) was a Usenet as well as an Internet pioneer. Horton made contributions in the development of Berkeley UNIX (BSD), including vi editor and terminfo database. He also developed the first email attachment tool, Uuencode, and was the driving force behind the development of Usenet in the 1980s.

The year was 1981 when Horton joined the ranks of the Technical Staff of Bell Labs in Columbus, Ohio. In Bell Labs she brought parts of Berkeley UNIX to UNIX System V including vi and curses. As part of her research concerning curses she created terminfo as a replacement to termcap (most of the work was released in SVR2). In 1987, she became part of Bell Labs Computation Center. Bell Labs Computation Center to offer officially supported Usenet along with Email for Usenet and Email to Bell Labs.

At Usenix in January 1984, Horton recruited a group of volunteers to create the UUCP Mapping Project. The project divided the world into geographic regions. A volunteer for each region maintained the region’s UUCP connectivity map and posted it regularly to the comp.mail.maps newsgroup. Each site ran Steve Bellovin and Peter Honeyman’s pathalias program to create a locally optimized email routing database from this map. Horton worked with Chris Seiwald and Larry Auton to produce the smail program, used this database to route email, using email addresses such as [email protected]

Horton is a transgender woman. Adopting the name Mary Ann in 1987, Horton founded Columbus’ first transgender support group, the Crystal Club, in 1989. In 1997, she joined EQUAL Lucent’s LGBT employee resource group, and saw the value of being “out” at work, supported by an Equal Opportunity (EO) nondiscrimination policy. At the time, no major company included transgender language in their EO policy. Horton asked for its inclusion in Lucent’s policy, and recommended the language “gender identity, characteristics, or expression”. As a result, Lucent became the first large company to add transgender-inclusive language to its EO policy in 1997.

In the year 1980, Horton brought Usenet’s A News system to Berkeley and started to promote the growth of the 10 sites network. In addition to the dialup UUCP technology Horton introduced support for Berknet as well as ARPANET and also added an interface between the well-known ARPANET mailing lists and Usenet “fa” newsgroups. In 1981, a high pupil Matt Glickman asked Horton for an idea for a spring break project together they designed and launched B News, which offered significant user experience and performance enhancements to keep up with the exponential increase in Usenet traffic.

Horton was born in Richland, Washington, and was raised within Washington’s Pacific Northwest. After gaining an interest in computer programming in the year 1970, Horton moved to San Diego County in 1971 and immediately discovered her love for California. Horton graduated in 1973 from the San Dieguito High School in 1973. After obtaining an BSCS at the University of Southern California in 1976, Horton went on to get her MSCS in the University of Wisconsin, and move into University of California at Berkeley. University of California at Berkeley in 1978. There she earned an Ph.D. in Computer Science in 1981.

In the mid-80s, the first domains used were .ARPA, .UUCP, .CSNET and .BITNET as top-level domains that represented the four main email services. In January of 1986, Horton represented UUCP at an assembly to plan technical cooperation between these networks. Other participants included Dan Oberst representing BITNET, Craig Partridge representing CSNET, and Ken Harrenstein, who hosted the event on behalf of ARPANET. Harrenstein convinced the other attendees to join in the formation of six top-level functionally domains, namely COM EDU, ORG, NET GOV, MIL. Each network was licensed to register domains within COM, EDU, ORG and NET. The registrars in this group were the predecessor for that of the ICANN the registry of domain names.

Usenet relied on email for replies, requiring that Usenet links could be used for email. At first, all Usenet and UUCP messages used “bang paths”, such as unc!research!ucbvax!mark, as email addresses. Horton guided this email process, including the use of the ARPANET/UUCP gateway, using routed email addresses such as [email protected] These addresses were complex, convoluted, and sometimes ambiguous. When Internet domains were first created in 1983, Horton championed their use, publishing the classic paper “What is a domain?”

In 1992, Horton created an internal email package for Bell Labs called EMS (Electronic Messaging System). This package integrated the existing UUCP-based email system with the AT&T “POST” white pages directory and the domain-based email world. She created and led a supported email service for Bell Labs. This system supported many email addressing formats, including those that dynamically queried the POST directory:
