The trick from the brick house — two-way built from one-way parts plus a control — has a lineage, and it runs through the same shape four times: a control element, a one-way channel, and the composition that makes them carry both directions. From a relay in 1835 to the internet today, it's one idea, re-instantiated in copper, then silicon, then packets.
A switch operated by another signal — the first controllable one-way valve. This is the "control" in the whole trick: the element that picks what flows and which way. The great-grandparent of the transistor-as-controllable-gate. Everything downstream needs this piece.
Telegraph lines carried one direction at a time. The question arises in copper: can you talk both ways on one wire? This is the two-way-brick-house problem, a century before the silicon — one-way channel, two-way need.
Send both directions on one wire (duplex, ~1850s–72). Then Edison's quadruplex (1874): four messages — two each way — on a single wire at once. Two-way (and four-way) from one-way channels plus control. The trick, fully working, in telegraph — and it quadrupled line capacity overnight.
Eight data pins carrying data both in and out, multiplexed by a direction control. The 74245 bus transceiver is the trick as a chip: two banks of one-way buffers and a DIR pin. The brick house, in silicon — same shape as Edison's wire, a century on.
One-way packet streams plus acknowledgment control, composing into two-way "connections." The same trick at planetary scale — every two-way conversation online is one-way channels with a protocol picking direction. Relay → wire → bus → packet: one idea, four substrates.
The through-line: controllable one-way elements composed into two-way communication. It isn't named after a person because it isn't one invention — it's a pattern that real inventions keep instantiating. Henry built the control. The telegraph posed the problem. Edison solved it in copper. Intel rebuilt it in silicon. The internet runs it at scale. Same trick, four eras, no eponym — because the pattern is older and wider than any one name.
